Pointer Pointer (2012) (pointerpointer.com)

I upvoted the submission because I think it's a cool trick either way.

Wouldn't that be complete overkill, though? Zooming and panning are so much simpler and less compute intensive.

We should have always known, as anything is possible at ZomboCom.

Another similar pointer idea from Moniker https://studiomoniker.com/projects/do-not-touch

The interesting bit is it keeps a list of the 4 point/images you've most recently seen, and will ignore those when searching for the new nearest point/image. Then scales that image to point at your cursor more accurately. This is why it feels pixel-perfect or so, because you won't get a repeat image until you refresh, or try the same location 5 times.

To test that out, ctrl+tab away and back to the tab without moving your cursor. You'll always get a different image. Then refresh the page, and ctrl+tab away and back again without moving your cursor. You'll see the same images in order.

Also neat that what was once a jQuery app now uses React and Typescript.

    const bruteClosest = (position: Point, positions: Point[]) => {
      let index = undefined;
      let closest = Number.MAX_VALUE;
      for (let i = 0; i < positions.length; i++) {
        const pos = positions[i];
        const distance = distancePoints(pos, position);
        if (distance < closest && !lastPicked.includes(i)) {
          closest = distance;
          index = i;
        };
      }
      lastPicked.unshift(index!);
      lastPicked.length = Math.min(lastPicked.length, 4);
      return index;
    };
