I am building a full size one as close to the DJ’s as possible. I have the 12" acrylic tube purchased . Im just trying to get everything done on this small one before I go diving into the same size one.

Ive got a number of designs to work but I would like to utilize the matrix to make some cool designs but its proving to be very hard.

Like it would be nice to make the eyes and rotate around the body of the cylinder but with “black” leds

Id like to just figure out how to do sprites or bitmaps but I cant find an example anywhere that uses the last_visible_led function.

If you go on instagram and search for someone named Designsbyp3rry he made the actually helmets for marshmello.

I believe the LAST_VISIBLE_LED define is to help keep the LED array size smaller than the full xy map. Just a guess based on the fact that the define is used in one place in the RGB shades code and that is when adding the leds in the setup function. I don’t see any LAST_VISIBLE_LED function. Just the define.
