A tiny way to compute a square / triangle wave at the same time without conditionals, only basic arithmetic and shifts.
This can be used for #oscillators or animations etc. #algorithm is a variant of HAKMEM 149.
Can also be used to draw a square. (And other shapes, see previous toot)
Code also shows how to draw a diamond shape by rotating the square by 45°.
There are two versions, optimized for size and optimized for speed.
