In my room I have mostly my own works:
-photo printed on canvas of the rear cluster of a bike (taken with a macro lens with some pretty vivid colors in the background)
-Acrylic on canvas painting...geometric design in primary colors
-Charcoal on paper drawings done as part of a series for an art class (I have 2/3...the 3rd one was ugly) Here is a kind of dark picture of one of them unframed:
Then I have a block printed flogging molly concert poster, a signed CD and case and a painting my dad did in design school.
In the hallway I have 3 of the newsprint spreads used in Matta-Clark's "Walls Paper"
You can see a stack of the prints in the foreground here...it was set up the same way at the MCA although they had run out of some of the prints when I got there.
In my cube at work I have 3 little water colors in the style of mondrian. I had done them in the planning of a larger project for an art class. They were in my bag when I moved in so I stuck them on the wall...here is the (hard to photograph) final piece:
It is enamel spray paint on glass with each color living on its own pane giving it a debth and 3-dimensional feeling (from tight angles you can see between the panes and the colors don't line up like they do straight on).
