I'm really into geometric DIY wall art right now. The top image is by U look like a bunny via Design for Mankind.
This photo is from flickr photographer Graphic Surgery taken somewhere in Sweden, also via Design for Mankind.
This is the dining room of Anne-Claire Rohe, whose home was featured on Design*Sponge. She made the hot pink wire installation as a homage to Fred Sandbeck.
There's a lot more out there, Design for Mankind is also really into geometrics. REALLY into. Design Crisis will also hook you up with a lot of fun graphic wall treatments, especially huge colorful ones that involve a major paint commitment and look best with gold. For example, this cool laser light show wall paint job, which is actually pretty subtle and very cool.
Anyway I'm thinking something maybe outside on my front porch? The kitchen is also rather boring, but maybe not after we put up the long-awaited liquor shelf?
