Make a LED matrix by disguising it as a solder exercise. The idea is to have a large gathering of modules on a wall that is constantly running and when the soldering is done it should be easy to just plug in one more module.

Buy cheap LEDs
5x5mm rgb 0,2 kr or
3,2x2,7mm rgb 0,23 kr
Source a cheap led driver
something like SSD1331 or something simpler like STP24DP05 (MBI5324 is a china clone of that one)

WS2803 3,30 kr drives 6 LEDs. Both dil and surface mount.

Profit!
