My votes go to Orangejuice and k0n.
Orangejuice - I found the light bulb with legs very surreal and kind of cute especially since it's trying to plug itself in. I'm trying to explain it, but I just enjoy the light bulb guy. 8)
K0n - I found the northern lights to be a nice touch. You have the moon, sun and northern lights together (not sure if that's possible) and it fits well together. Although I think the moon is a little too strong here, I like the pixellated area.
