An elegant bit of plastic, no?
Cheapy artwork - this is fabric (Ikea) stapled over a wooden frame I made (hardware store - two pieces of pine which they cut to size for free).
Okay, so you can't see the wooden frame at all, but you get the point.
I painted one of the fuschia walls white to brighten things up. Four foot tall vinyl decal from the dollar store: $2.00!
My wallet is happy.
