This 20 button mini remote control is the perfect companion for Raspberry Pi XBMC project!  It has 20 buttons and a layout we thought was handy: directional buttons, pause/play, volume and number entry buttons. It even comes complete with an included battery - Just remove the plastic pull-tab to use.
 
This little remote is also really handy for controlling a robot or other Raspberry Pi project from across the room.
