Looks awesome, but tens of seconds need to morph faster. By the time 4 is clearly formed and visible seconds read 48. While continuous motion is aesthetic, it is hard to tell time.
akovaski
The 4 actually becomes its true form at 40 (read the text below the clock), so what you were seeing was not 48 but rather 38.
primelens
Yes. Perhaps hitting the optimum form at 45 would be ideal. So 4 would start becoming clearer at 40 and then start degenerating after 45.

Or change the motion curve so that it stays in the recognizable state for longer, like 90% of the time.

I'd suggest capping the animation duration. 90% of 10 hours still leaves an hour for the animation.

If you've got an extended clock (days, months, years, centuries, millennia), morphing could take a while.

frigaardj
Currently the animations all last at most 20 seconds, irrespective of the transition duration.

Came here to say this. The "pure" version of each digit should come in the middle, rather than at the beginning, of its interval.
nyan_sandwich
Excellent.

It looks like it uses linear interpolation between the different glyphs, which makes it look a bit jerky. The author might want to try a sinusoidal interpolation so that velocity reaches zero at the key frames and the whole thing thus spends more time dwelling on the legible parts of the animation and looks smoother.

waqf
Or, y'know, a cubic Bezier interpolation.

One trick I've noticed to make animations/transitions "snappier" and more natural is to use quadratic/square (power of 2) scaling. For fun I did it on this clock just saving it locally - you can do it by modifying line 140 of `bezier_clock.pde` to square the ratio instead of simply assign it:

    animationRatio = ratio * ratio;  // can also replace with sqrt(ratio)
Again, just makes it a little bit 'snappier' (remember you have to hit spacebar to turn on continual animation), and scales it so you can determine the numbers a bit more clear earlier in the cycle because of the scaling on (0.0, 1.0]. This is certainly a fun piece of code to play with.

I've updated it with quad, cubic and sinusoidal modes. They all look good. Only problem is that because it's no longer linear, the various points can change at different rates and thus create 'kinks' in the curve. When it's linear, the 'line points' and the associated 'control points' are always in a line locally tangential to the curve (don't know the proper terminology but hopefully you understand).

That shouldn't happen if you do the motion transform uniformly on all axes. It should just be equivalent to changing the speed of time, rather than actually changing the trajectories.
devindotcom
Fun. I'd say you should have every number at x/60 or whatever of the way between first and next state, including hour and such, but that would probably just result in a bunch of unrecognizable squiggles.

edit: oops, RTFM devin

IneffablePigeon
Seems like you can toggle that by hitting space.

Edit: oops, three of us got here at the same time

It would be fun to have it on phones. Can you make an Android app? ;-)
pit
You could do it! Wrap an HTML file into a WebView Activity. The Android portion is pretty much:

    public class MyWebViewActivity extends Activity {
      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        WebView webView = new WebView(this);
        setContentView(webView);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("file:///android_asset/index.html");
      }
    }

I'm not entirely sure why this is being downvoted. It would make a pretty cool clock widget.

Nice animation. Something similar is JWZ's dali clock: http://www.jwz.org/xdaliclock/
sixothree
I sure do remember that being a lot more awesome at the time.

I think that is the first time I've seen Palm OS and Pebble Smart Watch in the same list
owenversteeg
Oh man. I still use my Palm Vx, and I'm going to put this on there as soon as I get home. Thank you so much!

Processing is absolutely wonderful. Be sure to check out p5.js as well [1], which has hooks into various HTML5 APIs including video and sound.

benjaminjackman
Pretty Cool! I wonder if it's possible / how hard it would be to port to Pebble.
__m
probably not that hard, but the resolution is pretty low.

Too bad, doesn't work without cookies/localstorage enabled.
mholt
Wow, that's awesome. Reminds me of Timely Alarm Clock[1] which I use every day and still tout as probably the single most beautiful Android app ever.

However, for this Bézier clock, it would be more practical if the animation was finished before it had to change again, so that we could read the numbers.

I _love_ timely. It's the first app I install if I ever need to reinstall my Android OS.

So pretty.

ctdonath
Apple Watch.

'nuf said.

ctdonath
Fine, naysayers. I'll port it thereto. A Bezier clock is briefly amusing on a web page, but will make a delightful functional showpiece on a watch.
femto113
I propose a new sport: Bezier clock golf, in which we try to construct a readable clock using the fewest number of control points. Current par is 5.
bruhlery
cool challenge, but how do you do less than 5 bezier points for the numeral 8?
colinjenken
Actually you just need 2 for creating an 8 if it's a closed spline. 3 If open.
femto113
Seems like open is a requirement, since not all the numerals are closed and I'm not sure how one would morph between open and closed spines. Playing around here (http://www.victoriakirst.com/beziertool/ anyone know a similar tool that has bookmarkable results so we can share work?) I'm thinking three control points should be achievable (haven't found a way to make a nice looking 4 yet, but most other numerals aren't that hard to pull off).

My crappy addition to clocks: http://myoldclock.appspot.com/

Did it in about 12 hours for a Google I/O competition 3 years ago. It's a countdown clock instead of a normal clock, but similar idea.

RoboTeddy
I wonder what it would look like with interpolation pathways that minimize the amount of bending
arketyp
I image you would become used to reading the interpolated states eventually. That would be a pretty nice way to write fractions.
bitwize
Right now jwz is slapping his own forehead going "bezier curves! Of course! Why didn't I think of that?"
jlward4th
Doesn't work unless cookies / local storage is enabled:

Uncaught SecurityError: Failed to read the 'localStorage' property from 'Window': Access is denied for this document. processing.js:9503

Not sure why processing.js needs local storage to work.

chillingeffect
The graphics are excellent.

I'm curious about the code organization: it seems that processing.js contains both the application code for the clock as well as the libraries for interpreting the Processing code. Is that true? Is that the best organization? Would it not be better to have have a processing.js which is the interpreter/libraries and a bezier_clock.js?

tslater2006
Per the Processing.js site, you include the processing.js file and then set an attribute on the canvas showing where to get the PDE file (your code). In this case they set it to: data-processing-sources="bezier_clock.pde"

Making the sources to the clock available here: http://jackf.net/bezier-clock/bezier_clock.pde

chillingeffect
Ah! I see now. Thank you very much for explaining that.
myhf
Ahh, it was so satisfying to watch it right as 59:59 ticked over to 00:00.
Tloewald
Cute, but I would prefer if the tweening were adjusted to dwell longer on the numbers when less distorted.
