• Users create 3D "Worlds" that run in the browser.
• Worlds are in JavaScript and use browser WebGL graphics.
• We support 3D and 2D graphics, real physics, and import of pre-built 3D models.
• Worlds may be for humans to interact with (games, demos).
• Or Worlds may be for programs to interact with (teaching exercises and student answers, competitions).
• Worlds can be "cloned" and modified by other users, in a new type of "social coding".
• No install. Worlds run in the browser. Worlds can be edited in the browser.
• Runs in the browser on mobiles. No app needed.
• You can write mobile touch games. You can play your creations on the bus. You can code on the bus.
• Worlds can be embedded on other websites. Show off your creations on other sites.

We have three types of users:

1. Programmers who can write entire Worlds from scratch.
2. Users who just browse and run the Worlds.
3. "Tweakers" who cannot write an entire World but are able to change a few lines of code of the Worlds written by the programmers. Why not? What's the worst that could happen?

Start as a "tweaker". End as a programmer!
