3-D virtual world



Hi guys, I'm back now. I have the great news that I am now a VPython programmer! (For those of you who don't know what it is, click Here , and be amazed). Python is a computer language that allows you to communicate directly  to your computer and have it do exactly what you want.It can add numbers, reverse words, and even draw.  But VPython is the real deal. The V stands for Visual, meaning 3-D virtual things. It allows you to maniputlae 3-D geometrical shapes, and have them move around. Shown is a screen shot of my masterpiece. I wish I could have them moving around in the backround, but that is beyond me :P. If you would like to see it in its entirety, click on the previous link. There it says: Download: Free downloads for Windows, Macintosh, and Linux. If you are using Microsoft, click Windows. If you are on an apple device, click Macintosh. And for those gifted few on Linux, click Linux. You should download the latest version if you do have the guts to download it. When you've finally opened the fidgety thing, copy and paste the following code:
