Topic awaiting preservation: December 20lines Javascript Contest - Colors - Entries

This month's theme is: Colors.

The colors can be animated, static, ugly, pretty, interactive, ... I just want to see some colors on more time before a snow coat covers the Asylum.

A code monkey said once:
As usual, the main rule is to make your script in 20 lines of (effective) code.
Comas shouldn't be used to execute several instructions on the same line
See the code sample below to illustrate the basic rules :

code:

---

<script type="text/javascript">



/* */ document.body.onclick = function()

/* */ {

/* 01 */ val = prompt( 'enter a number' );

/* 02 */ for( i=0; i<10; i++ )

/* */ {

/* 03 */ alert( stupidFunction( val, i ) )

/* */ }

/* */ }



/* */ function stupidFunction( a, b )

/* */ {

/* 04 */ return a>b?a:b; // I said it was a stupid function

/* */ }



</script>

---

The document.body.onclick = function() does not count as a line as it's not some effective code and the function call could be put in the BODY tag ( or anyother HTML tag ).
The declaration of the stupidFunction() does not count either for the same reasons.
The coma in the line /* 03 */ is ok, since it simply separates the parameters of a function.

Examples of possible entries :

• plasmas,
• color scheme generator,
• Dutch Color Scheme generator,
• Fireworks,
• Mondrians,
• ...

As usual, try to submit your entries here, and your comments in December 20lines Javascript Contest - Colors - Comments
I hope you'll enjoy this topic.

Sheesh, y'alls boring.

Here's my first entry. I have another idea on me, I'm just trying to figure out how to squeeze it into 20 lines without doing 0 * (var a = foo) + 0 * (var b = bar); or whatever, since I feel that's cheating.

(Yes, I know the depth ordering is backwards. It looks cooler that way. )

Here's mine, then. The bad news: It's Mozilla only, and it needs a stupidly fast computer to run. The good news: It is, I believe, a world first - Realtime GIF generation in Javascript.

GifPlasma

I was hoping this could be my secret weapon at next year's Assembly browser demo compo, but I haven't been able to get it working on IE, which kills that plan stone dead (for now). So, I'm sharing it with you all as a Christmas present. Who knows, maybe some genius here can figure out how to make IE behave, and then it can be my not-so-secret weapon at Assembly...

More details of the inner workings will come soon - I think this will need a thread of its own.

to view my entry, please promise me two things:

1. dont view it in a mozilla based browser, cause the javascript performance is slow as a dead snail. better performance is with IE or opera!
[edit: several people reported very good and smooth perfromance in mozilla too. hooray! ]

2. dont view it if you are an inmate because of epilepsy.
