Gold wave
Ashish Cube Wave reminds me of Johnno's Gold wave that I think he got from Basic256. Here is my mod of that:

I am wondering why I never translated it to QB64? Maybe because I haven't figured out an equivalent of drawpoly yet.

Seems so much easier to to do it with drawpoly!

You might want to see if the Three Amigas at are interested in pursuing a _DRAWPOLY statement. I suppose it depends how involved it is. This is somewhat a touchy area in BASIC, as part of the philosophy is learning how to use existing code to make such things occur. Sometimes it is nice to have such functions / libraries packaged in a keyword statement. Ah, decisions, decisions.

Very pretty results. Reminded me a bit of Mine Craft.
