Look at #uxn perform!

Short jokes for short laughs. #uxn
Another page from the uxn tutorial notes.
It explains how to add, subtract, multiply and divide bytes. uxn notes: "It's easier to read the stack horizontally" and kicks a bucket.
It also explains how to calculate shorts and makes a dumb joke where two actual shorts are added.

And while I'm here, these are my notes on #uxn 1 bit per pixel sprite encoding.
A page showing three grids that show the conversion from pixels to hex numbers.
It says: A 1bpp tile is a set of 8 bytes that encode the state of its 8x8 pixels. Each pixel can be on (1) or off(0).
There is a drawing of a uxn balloon dropping pixels onto a little construction site.

Double page incoming! Drawing #uxn sprites in 5 easy steps!
A page from the uxn starter tutorials showing steps 1 and two to draw sprites: setting up the devices and the colors. It shows a drawing of varvara painting four color dots.
The second page showing the next three steps: setting coordinates, the memory address and drawing the sprite.
It shows uxn with an envelope and varavar opening it. It contains an image of a heart.
