Developer Builds Custom GUI for Bare-Metal OS Running in L3 Cache

A developer created a double-buffered graphical compositor for their V.E.L.O.C.I.T.Y.-OS, a bare-metal operating system that runs entirely in CPU L3 cache. The Synaptic Canvas GUI includes three swappable engines: a Glassmorphic Shell, a Matrix Rain display, and a force-directed spatial interface. The project demonstrates low-level graphics programming without standard libraries or floating-point units.
