[Swlug] Another phallus?

[Rhys Sage]

I have just reworked my original 20' blue LED phallus on the top of the shipping container. After 2 years the solderless breadboard failed. The contacts got rusty. The relay board I was using also has rusty connector pins. The Pi Pico after 2 years is a bit grubby but will now be repurposed as will the relay board. The breadboard is destined for the bin.
I replaced it with a custom circuit which has a TIP120 doing the high-side 12v switching, a buck converter (of which one of the 4 bought from ebay actually worked), a diode and a resistor. The CPU is an ATTiny13 which was challenging to code. I ended up writing a python program to generate the C++ code I needed.
It's all in a little plastic box and protected more from the dampness of my outdoor concrete cupboard.
Having done that I'm busily 3D printing a gimbal to use with two servoes and a laser. I'm going better!
This time the plan is to use either the Pico or an Arduino or an ESP32 or even an ATTiny88 to draw a phallus on the side of a building or eventually on the underside of the clouds on an overcast day.
I never tire of being a rebel!
Has anybody coded anything like that before? I've not looked but would not be amazed to find that since this is just like a 2 dimensional 3D print, somebody has already got software to do this and all I have to do is to put a drawing into Tinkercad or similar.
