I managed to get hold of some tiny tin arcade cabinets that contained sweets. Rather then put the empty tin into a drawer, or on a shelf, I decided to modify it into a tiny clock.
Using a tiny oLED display, an arduino and an RTC (Real Time Clock), I cut away the parts needed and fabricated new ones out of black styrene. Add 2 buttons for UI purposes, and some code to display the clock faces and the unit was complete.
The default clock face is a game of PONG. This works by the minutes on the left incrementing when the hour side looses. Same for the hours incrementing, the minutes loose. In the meantime the display is showing a game of PONG for 59 seconds.
Alternative display - Pacman. The ghost catches Pacman and the time increments.
Alternative display - Tetris. The display shows a game of Tetris that when lost increments the time.
Components - Arduino, oLED display, 2 micro tact switches and a RTC module.
