I read today that a new version of Unity, a 3D Platform for the web, was released yesterday. It is full of new features, but most importantly, it is now free. I've been meaning to download the trial and experiment with this for a while... Now that it is free, there's no longer the worry about the trial expiration.
From the site:
Unity is now available at no cost at http://unity3d.com/unity/download to make it possible for all developers to get access to the best development platform available.
Unity Pro, Unity Wii, Unity iPhone Basic, and Unity iPhone advanced are not free, however you should still be able to plenty of cool things on the web with the free version.
Download It Here:
I've gone ahead and installed it to see what it is capable of... let's hope I can come up with some good examples for developria.com. :-)
