Here's a fun lamp that you can build yourself. It's made of flexible plastic and comes in three styles: T-Rex, triceratops, or diplodocus. I chose the T-Rex, and he is currently guarding one of our rooms. :)
All of the pieces pop together. No extra tools are needed for this. The lamp kit comes with the cord but not a bulb. So, you'll have to pick up a small night light bulb. This is a perfect piece for a little boy's room (or an adult obsessed with dinosaurs). I ordered mine from Amazon, but these lamps are also available at Think Geek.
