Damnit, I come on the BBS to find that reference to the iPod connector specification, and I end up many hours later with no less than five Wikipedia pages about abstract mathematics open on my desktop.

Playing the above game made me double check the Fibonacci sequence in Google, where I innocently clicked the Wikipedia entry "just to see what it would say." Led me to Diophantine equations, Hilbert's 23 problems, Hypercomputation, Malament-Hogarth spacetime, and the definition of a worldline. At that point, I realized "worldlines" were what I'd thought up when concluding that the fourth dimensional view of an object, using atoms as the measured units, is infinite and, the time before and after the object "exists", its atoms belonged to other objects.

Yup, there went my Sunday afternoon. Now, let's finish that iPod integration design drawing I started hours ago...
