A Mac OS 8 emulator running in the browser, complete with a working IRC client and Netscape 2.0. The emulator runs real 68k Mac software via a WASM port of the Infinite Mac emulation stack.

A decentralized identity system that let anyone log into websites using their email address — no passwords shared with third parties.
