Constrained by the bounds of your imagination and physics. Like errrm.. Art!

> Not much fun.

I think that needs a qualifier: "according to me" or something like that, I personally think science is great fun.

Huh? Creativity is what humans do! For everything else we find a way to build machines to do it (or enslave other humans :-)).

There are very good arguments that constrained creativity is the best creativity -- or perhaps the only creativity. Just choosing a medium or style for your art is constraining. Making a web page is constraining, making chocolate cake is constrained by certain parameters.

I think what you're looking for is "expressive" -- and I'd agree, scientific discoveries are by necessity creative, but usually not expressive. But that's not really an aim...

Ballsy thing to type on your own 3000 MHz computer.

That's the kind of balls one earns by skipping too many science classes - one derived from a marginal understanding of the world around them.
