Bomomo is a drawing program written in Javascript (thanks Stéphane). It doesn't work in Internet Explorer, but then, who uses that? Cubescapeis a 2.5D brick building program written in Javascript. Meebo is a meta-IM client written in Javascript. Impressive!

Apple just announced that they are working on making Javascript 60% faster in WebKit (in other words, in Safari). And they have a legitimate business interest in achieving this. So does Google.

Maybe your next game could be written in Javascript? Remember: not just browser eye-candy, real programming language, no real relation to Java.
