I once (badly) did something similar as a student [1].

Unfortunately it's in Matlab so I can not run it any more.

You know a personal license is only $149 USD right? You could then run your old code. Toolkits for home are $49.

$149 is still a significant amount for many people. Especially for something non-essential.

If you want to run it again you could try Octave, an open source Matlab alternative.

I also made something similar using Python a long time ago [1]. It's a extremely simple script so it should still work.
