If you're a fan of abstract pictures, art and or anyone in my family.... check my sister's blogsite out. She takes, sometimes messes with, abstracts, and then posts all kinds of pictures.
From beautiful colourful flowers, to black and white animals, to cartoonish versions of old pictures to pictures taken through a dirty window while driving... It's all art, and I find it quite interesting and beautiful. This isn't a pitch to sell her stuff, but, she does, and it's good stuff. She has an ETSY page (what's ETSY? Wikipedia explanation) where you're able to buy all sizes of prints, cards, and even matte prints.
Just have a look at her blog to see what I'm talking about, no purchase necessary.
