Anyone try Clara.io for Modeling?

[RimReaping]

It's an online too for modeling. I haven't tried it yet because it requires you to sign up for a free account, but apparently it is totally free to use. Has anyone tried it? It's all done in the browser, and doesn't require you to download any software. It allows you to create 3D models that can be used in printing, and then you can share them on the net. I'm guessing they are utilizing some sort of "thingiverse" type free market for designs, but I'm not sure. They are currently in beta.

I was looking at their facebook page and they have like 80,000 likes. Seems like they have been around a while, so why are they in Beta?

Here are some photos of things made in the software. Pretty impressive.

Looks like just the thing I need to finish my current project.

I'll play around with it for a bit later.
