I can't help but roll my eyes here: "I wish all those people painting canvases would paint my living room... now THAT would be useful." This seems to come up every time there's an art project featured on HN. It's art people; it's its own point!

Besides, the fellow did actually seem to have a use for this (scaling up/down, zooming) tho most of that stuff could be achieved more simply with image. Anyway: Hackers -> use tech for fun, not just utility.
