October: conceived of the idea

October: built the first prototype

December: miniaturized the prototype

January through March: absolutely nothing

April: revisited the math and improved the stress-sensing algorithm (which code will eventually be made available publicly as soon as I master the squelch algorithm; anyone who wants to help can have it now).

By August 2015: to complete the three main tasks required.

By November 2015: to complete playtesting with a statistically significant number of individuals from all subgroups (that's a large number).
