Started playing around with the newest release of Silo, & besides a few perplexing bugs (saving files to an unopenable extension?) it's a great modeler. Lightweight, with most of the commands working the way you'd like them to, plus the ability to retopologize your mess of a mesh puts Silo at the top of my list when all I want to do is sketch out some ideas in 3D. This weekend I started a layout for a quick little short with the Incredible Hulk and this was my first rough pass at a cartoony proportioned Hulk. So much more to do in terms of fixing muscle masses and getting edgeflows correct, but it was lots of fun.
