I went, for two days! It was pretty awesome. Got to check out a bunch of booths such as the Autodesk booth, Lightwave, C4D, Vue, Brazil, Vray, Final Render, Gnomon, VFS, Daz3D, Keyshot, Pixar, Rythm and Hues, and more! I was a big fan of the Lightwave stuff since I'm really into that, but also had a great time playing with 3Dconnexion's 3D mouse. Check it out
[link]I hope to go next year and spend more time and have more access. All in all it was a pretty inspiring experience.
