very cool! i've done a bit of video art in quartz composer but i hadn't even thought about using it for prototyping. such a versatile tool, i hope apple doesn't abandon it
After that Cooliris and now back to entrepreneurship with Everpix :)
On the other hand, why doesn't anyone ever do a tool startup anymore? Its all about content production and consumption these days. If say, you did PixelShox in 2013 (assuming QC didn't exist), could you get funded as a YC startup?
