[RESOLVED] [Half-Serious & Urgent] weird equations & graphs

Hi all,
since my post doesn't really belong to Math forum I decided to post here.
I need an equation with weird looking graph, remember I just need the equation.

Please HELP

What do you consider a "weird looking graph"?

for example sin(5*pi*x)+cos(6*pi*x)

x³ + y³ = 3axy is a weird graph, but i don't know how you'd plot it.

The plot thickens...

x = 3 ... thats just plain odd when ya graph it...

How about a 3D graph?

I'm on edge just looking at AndrewG's graph, I'll axis friends if he's this smart in person too.
