Random Tessellations - bplus - 05-09-2023
Inspired by Charlie's BAM version I started from scratch for QB64 version with added full colorization mode.
Use b key to toggle color modes or esc to quit, any other key shows another random tile tessellated screen:

' 1. a mod of Charlies version with different pixel block size with black backgrounds
' 2. the colorized version which reminds me of Magic Eye Art

Tessellation madness, because I couldn't help myself.
"x","X","y","Y",",",".","[","]","-","=" all do something. Maybe this could be made more coherent, but what fun is that?
EDIT: commented out DEflng, shifting X&Y works now.

LOL this last one listed was funny. I like how it reacts while zooming out, then zooming back in to get the junk of particles again.
RE: Random Tessellations - bplus - 05-09-2023
Nice mod @James D Jarvis
I haven't figured out what x, y do because screens are different every time press spacebar = new pattern but [] is obviously changing the size of "pixel" block.
BTW did you notice the DefLng A-Z so you have to be careful if you want Single Float type calculations ie changing x and y by .1 wont do much until they accumulate an integer amount.
RE: Random Tessellations - mnrvovrfc - 05-09-2023
I made changes so "xs", "ys" and "scale" and the local "x" and "y" of the subprograms were single-prec. It didn't make a lot of difference in the program output.

Thankyou, you saved me from that very experiment
I also tried a pixel off set in my code in attempts to draw patterns on diagonals but something was wrong minded how I did it.
I think setting a background black color 1/3 to 2/3 of time might make colorful tessellations more "meaningful" by looking more like an object with a background instead of a wall texture as James has done tiles of balls.
Update: Yeah with black background more often it looks more "patternly" Limiting colors is maybe a rabbit hole? But here in Tessellations 2 I use 2 pallets for color filled tiles. One pallet is in blues and white then other darker red, green, yellow/brown:

yeah there are a couple problems I likely wouldn't have introduced if I had not been eating lunch at the time.
Just commenting out the deflng seems to work in my crazed hack.
