G'day Atro,
Try the following in a new Tiddler:
<$vars thisSecond=<<now ss>> >
<$vars rgbArg1={{{ [<thisSecond>multiply[3]]}}}
rgbArg3={{{ [<thisSecond>multiply[5]]}}} >
<div style={{{ [[border:25px solid
rgb(]addsuffix<rgbArg1>addsuffix[,]addsuffix<rgbArg1>addsuffix[,]addsuffix<rgbArg3>addsuffix[)]]
}}}>
Some Text
</div>
</$vars>
</$vars>
You'll need to do something to re-render the tiddler and see how colour
changes over time. (I just wanted a quick way to show how to have dynamic
CSS styling using TiddlyWiki filtering. So nothing fancy just for
demonstration purposes.)
