Nice blurring!
u/iverjo

The blur wasn't meant as a part of the effect. I believe it was done as a compromise to save a few bytes at a point during the process of creating the dweet

u/keithclark

Try changing 1.2502 to different values for different patterns. For example: use 70.286 for death star
u/PeteAJ

A little confused by the for loop. The second statement just defines the variables d and e?

@PeteAJ I've used the same for trick before -- if either of a+t or b are zero, their sine is zero so the product is false-y, which terminates the loop
