Miffy surprise

Fig.1: real bunnies. Once upon a time (in a galaxy far, far away), Miffy emerged as the next evolutionary step out of these proto-rabbits.

Fig.2: Miffy.

Fig.3: "what is playing now" bush, front. While Miffy performs on stage, the viewers would surely like some indication of which song is currently playing. Hence, this bush; LEDs indicate 1 out of 3 'main' tunes, or an 'intermission'-tune.

Fig.4: "what is playing now" bush, back. Wiring is modest; 4 wires for 4 LEDs, with shared kathode.

Fig.5: when time is a factor and sleep a luxury, Coke is vital.

Fig.6: lightshow-bush, front. Nice LED 'walklight' (what's this called in English?) is displayed here with a few different modes.

Fig.7: lightshow-bush, front. Wiring is slightly less boring, with 4 series-chains of 4 LEDs each.

Fig.8: the board. Not extremely interesting is it: a relais, an MCU, a transistors for each of the 4 'walklight'-channels, a zener, and a few resistors.

Fig.9: a snug fit. Everything is designed genau wie die Profis as they say in France, to fold together into a box-shape. Electronics is hidden under the 'floor' on which Miffy stands.

Fig.10: action! So ok, victim opens/unfolds the box, presses button, and is amazed. Mission accomplished. Congratulations.

So... WTF?!

well.
