Function for triangle-wave y coordinate (oscillate between 0 and m).

y = m - abs(t % (2*m) - m)

Where:
y = output
m = max value (peak)
t = time

"Standard" character ramp for grey scale pictures, black -> white:

"$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1{}[]?-_+~<>i!lI;:,"^`'. "

A more convincing but shorter sequence for representing 10 levels of grey is:

" .:-=+*#%@"

For direct image URL, the image quality is much lower than the original upload (the resolution and size of the original upload can be found in the right sidebar). This is not the case few years ago when the original image was accessible through right click, but on 2017, Wix acquired DeviantArt, and has been migrating the images to their own image hosting system from the original DeviantArt system. They linked most of the direct images to a stripped-down version of the original images; hence the bad image quality. Below are the three different formats of direct image URLs I found:

• URL with /v1/fill inside: this means that the image went through Wix's encoding system and is modified to a specific size and quality. In this case, you remove ?token= and its values, add /intermediary in front of /f/ in the URL, and change the image settings right after /v1/fill/ to w_5100,h_5100,bl,q_100. The definitions of the values can be found in [Wix's Image Service](https://support.wi

Ben and 2 Divides
Two years ago, Ben Weiss (the guy who wrote Kai's Power Tools, Goo, Soap, etc.) was telling me about this idea he had to combine two divides. I just didn't pay attention.
Luckily, he told me again.

Ben's idea is really simple, and I use it everywhere now.

2 divides at once
Suppose you want to compute:

			renderer = P2D;
			break;
		case "processing.opengl.PGraphics3D":
			renderer = P3D;
			break;
