That's not just a GUI -- it looks like it supports alpha transparency. That's certainly more than I expected out of a floppy disk.

Well, I assume they're usiing straight-forward, direct-to-memory framebuffer manipulation. No X protocol to get in the way, no unavailable GPU drivers. Simple alpha transparency shouldn't be hard to do. When did Porter and Duff write their paper, '83?

You can do a heck of a lot in 1.44MB. The original Mac had a complete GUI plus some applications running from a 400K floppy, plus a 64K ROM.

People forget.

Adding alpha transparency for a framebuffer based GUI need not take more than a few hundred bytes.

A few hundred bytes is precious space on a floppy.
