Is it possible to download some of the really early unity versions?

Personally I would love to be able to download some of the really early unity indie builds, just to see how much this program has changed, and It seems like it would be a great learning experience.

I looked through the previous versions they offer here, but I can’t find anything below 3.0 builds.

Take a look at this thread: http://forum.unity3d.com/threads/73388-Unity3D-all-versions-of-the-download-link

For windows: http://download.unity3d.com/download_unity/UnitySetup-x.x.x.exe
For Mac: http://download.unity3d.com/download_unity/unity-x.x.x.dmg
Just replace x.x.x with version number you want to get.

Just remember that, if you’re using a PC, the first Windows version was Unity 2.5

And the really early versions don’t work on OS X either, or at least not when using a recent version of the OS.
