Every character in a block of ASCII art has a visual weight — @ fills its cell, . barely touches it — so fetch reads those weights as heights, turns your distro’s logo into a relief and spins it in the terminal, shaded, beside the usual kernel-and-uptime readout. Click and drag to turn it by hand, let go to fling it; any keypress stops it and passes through to the shell, so it works as a startup fetch. One file of C, no GPU, no graphics library; Linux and macOS.
