20-word Description: Just Leap In brings innovation to 3D worlds on the Web, combining simplicity, next-gen visuals and physics, multimedia sharing and social networking.

CEO’s Pitch: We use the Web every day to check on friends, browse multimedia and news, and discover new people. Just Leap In aims to bring that daily simplicity to virtual worlds, on any webpage. When you land in JLI, we want you to feel like you’re smack in the middle of a social community where you can express yourself, upload multimedia, and link to friends – not in the middle of an empty island. And unlike other Web-delivered virtual worlds, we’re already delivering next-gen 3D graphics and physics to both Mac & PC, Firefox & IE.
