Once upon a time I have bought USB modem. Mobile operator logo was too boring for me and I decided to make it more fun :)
So meet Futurama Bender style modem!
1) USB modem (pref. white color)
2) File or sandpaper
5) Lacquer or spray paint (clear)
Step 1: Prepare surface for drawing
Clean operator logo from modem surface using file or sandpaper. Wipe surface with some degreaser.
(Sorry, I have forgotten to get photo of this step. So it's just photoshoped picture)
