Okay. Since I'm posting on my sister's laptop, and she's got 2.46, here's the start-up screen for it:
This is the start-up screen for Blender 2.49b. If you press a key or move your mouse the slightest bit, the thing with the weird orange alien guy would dissapear.
This is the start-up screen for Blender 2.5 Alpha-2. You can see all of my files up there. Game Engine Tutorial 3...Sundial CIty...Gravity Guy...
This is the screen for Blender 2.5 Beta-3. The newest-and so far awesomest-version of Blender. And I thank Ben for showing me how to do screenshots.
