Try it out for an hour or too and you'll soon see what I mean. It is the most creative tool I have ever used. It's not a 3D modelling tool in the conventional sense it is a real-time 3D sketching tool. Of course you can sketch really complex things with it given enough time. But it is a whole different approach.

I wish they did a non-professional "lite" version for people like me who just want to play with it..
