For Task #4, we’re going to continue the theme… We did a twinkle, then a drip, then a lubdub beat, and now we’re going to make a ping.
What should it look like… A spot (your choice of random or center fixed) that gets bright, and then radiates outward like a radar ping, sending a wave of energy rippling away from it, decaying in strength, as it moves away.
We’re going to expand on this once we get into Matrixes. But this one works even for a strand.
