yeah I grabbed the free version a couple weeks ago and tinkered with it a bit. I have not had a lot of free time to play with it. I was on my youtube page and saw those vids and thought they were worth sharing for folks that have more time and creativity them me.

It makes really heavy models but it's kinda of fun for seeing what kind of interesting shapes you can make and like he says in the video you do not have to worry about poly flow while you are working with the solid objects, so you are free to experiment and create lots of different forms. It is kind of like playing with a 3D spirograph toy.
