craftgrrl | ugh, any fun crafts? ( just finished glow under blacklight rainbow ball :D)

I've been feeling really depressed and blah lately. I want to do something crafty, something happy crafty that preferrably doesnt need any expression from my side (otherwise it would end up black and blah lol)

normally i would sew and make a plushie out of plain cotton and then paint it or something but im kind of tired of making plushies, they just end up lying around and after stuffing them im always to lazy to sew them close.

I would prefer something that doesnt take forever either, because i never finish crafts that take to long xD

any ideas anyone?

[edit] I have just finished my styrofoam rainbow ball :D pictures behind the

teh rainbow:

my workspace after finishing:

rainbow ball posing with my blacklight :) the pink dots actually glow more orange tho.

i colored the styrofoam ball first just with water paint (as you can see in the box in the last pic) and then i mixed glue with waterpaint to make all the fancy symbols on and all, and the rainbow.
i am VERY sorry about the crappy pics but i really cant afford a fancy digicam or anything so im stuck with my webcam :(
if you think the pics are to unclear just tell me ^^;; ive kind of never posted any of my crafts before because of my picture crappyness..
oh the colors on the rainbow are red, orange, yellow green and blue, the symbols and dots on the ball itself are blue green red yellow and bright pink.
