You're right, 3D CSS still has a usecase though, it's just very restricted. Clara.io looks like a pretty sweet tool btw!

Be sure to apply for the beta, I can let you in immdiatel....

Clara.io is built using ThreeJS as your article recommends. I'm actually the third largest contributor to ThreeJS by commmits, so we are giving back where it matters too.

I have built a very specific product preview with 3D CSS (http://www.foldable.me) and have experimented some more with 3D CSS, but struggled to find a usecase for it (other than some funky UI animations).

Thanks! I couldn't figure out how to do the colors in the SASS loop.
