Ughh... the language, unreadable.
This is the Internet, not everyone speaks perfect English. The article is actually quite good, relatively speaking. You'll get used to it eventually if you read enough. :-)

Thankfully, his knowledge of English (which I'll bet is better than your knowledge of Japanese) did not stop him from giving translation a go for our benefit.

Why not contact him and volunteer your stellar English skills to make these project write ups better?

Also you used a comma where a semi-colon was clearly in order. Bastard.

He has a lot more very interesting projects on his website.
The URL sounded familiar... now I know why. ChaN is the person behind FatFs, an incredibly good embedded File System module. Currently using it on ChibiOS and very happy with it.
Would it be possible to use three color lasers, and create full-color images?

On a second thought, that would probably require variable brightness, or being fast enough so you can move slower on regions you want to appear more bright...

You could include an LCD shutter for each one and use dithering.
Interesting project, but potentially very dangerous. If you get the laser power wrong then you end up blinding everyone in the room.
Maybe blinding Somebody in the room. "Don't run with that pencil, you'll put your eye out!"
The most interesting about this project is the feedback of the motors. Knowing the position of the motors is making this very accurate.
