[http://www.youtube.com/watch?v=D5PS-zOciF8 The original Secret Motor] was a project by Mike Kan circa 1993 to visualize memory access on a Macintosh using an oscilloscope. The [https://github.com/leif/qemu-secret-motor QEMU Secret Motor] is an attempt to create something similar using an emulator. It currently consists of a patched version of qemu which prints the x86 EIP for each cycle of the emulated machine, and a python script (based on this [https://www.youtube.com/watch?v=s1eNjUgaB-g YouScope] [http://www.youtube.com/watch?v=-1E0DpQ_cFo emulator]) to visualize that data.
