Keep it simple and pick a thing that already exist and you think is just too good not to have or go creative and pixel an all-in-one device suitable for every purpose!
You may even pick the finished thing as your avatar for a week if you want. (10kb limit for avatars!)
Canvas Size - Exactly. 64x64
Colours - Max. 12
Transparency - Required.
