This is Electron Microscope 3. It's a GUI for the console version of Folding@Home. It is no longer supported by TheWeatherMan nowadays, but Howieh of Team Helix has posted a new emprotz.dat file, that is included here. So if you liked EMIII but stopped using it because the data wasn't working this will sort it out.
Thanks go to Howieh for the reincarnation of EMIII.
