I am learning to draw in SketchUp these days and made myself a nice clock in the process. The clock displays local/UTC time and a time-based one-time password for a selected 2-Step verification account.
The clock consists of a 3D printed case designed in SketchUp and printed by ShapeWays in White Strong & Flexible material, a Raspberry Pi, LED seven segment/dot matrix displays and some chalkboard paint. The python code uses the excellent MAX7219 driver by Richard Hull and onetimepass by Tom Jaskowski.
