Wow, I was not expecting that. This is fantastic. Hold down your left mouse and keep it still and it changes colour and starts getting more intense. Great job!

That one is actually pretty "old" already. The original demo can be found here: https://developer.mozilla.org/demos/detail/fluid

I'm just wondering why this is impressive. Is it partly because it's Javascript and it's in a browser? I mean, would it have been just as impressive if you had to download a C++ program and compile it to get the same thing?

This does not work for me in FF 22.0 (work specified version). Looks nice in chrome, only time it drops is when you bundle them into a large group and then cross you mouse over it and they explode everywhere.

It's working for me in FF 24.0.

Doesn't work for me in FF 24.0, Windows XP :-(

Should I enable something in about:config or something else ?

I'm obviously being stupid - but what do I have to do to make this run in Chrome?

Hazarding a guess: Not use linux

I've never had webgl work on linux (not that I've tried particularly hard)

It's working fine for me on the beta channel without any experimental flags enabled.

I'm on OSX. I tried some different flags but I've obviously missed something.

Earlier quoted context omitted.

Browser info?

I've got the same problem: Version 30.0.1599.101 Chrome on Mac OS X Mavericks. I believe the problem is your time() method on line 189 of script.js; there's no element with id "time".

Time is a self-referencing function. That shouldn't be breaking it.
