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
(Sorry, I have forgotten to get photo of this step. So it's just photoshoped picture)
Step 2: Draw picture in pencil
As a big fan of Bender from Futurama I decided to choose this awesome character.
Disclaimer: I don’t have any talent for drawing. So I googled for Bender picture, printed it with certain zoom (to fit modem size), cut picture and outlined it with pencil on modem surface.
Step 3: Finish surface
