While at the store recently my roomie said "Hey! If those were blue they would look like tardis lights!" So I bought four and now we have awesome tardis lights for our garden.
solar powered garden lights (WalMart)
metallic blue spray paint
piece of Styrofoam
Carefully disassemble the garden lights. Remove the white plastic window piece and set aside.
Using masking tape, tape off the solar panel and the lightbulb. Poke the stake end into the Styrofoam and arrange other pieces onto a covered surface.
Apply a coat of spray paint and allow to dry. Follow the directions on the can for applying multiple coats. Reassemble once completely dry. Now we have solar powered tardis lights in the garden. Taaah dah, geekage accomplished!
