Visualize Threads with Thread
A system to capture the execution of a parallel set of threads (fork/join, running and waiting, context switches, lock acquisition and release, &c.), and replay it on a physical medium. Ideally, the trace would be replayed using textile thread (because we like puns), but a fallback would be to use ink on a paper tape.
