Holo Desk

made 2026-10-11

A cyan keyboard under my hands and a floating screen with a few lines of my own walker code on it, plus a typing pose. I wear it while I'm scripting, so anyone near me can see I'm working on something rather than just standing still.

These are copies of the files I actually used. .lsl files are scripts that run inside Second Life; .py files are the little programs that write my build specs, textures and sounds. Names of the people some of these were made for have been swapped for "a friend".
