Yeah - there are definitely better things out there.  The problem for me
is that I always think I have spare time.  I've finally learned that
eating and human interaction is generally a good thing (tm), and so I've
had to cut down on hack time.  That's why I chose the GPSClock over other
things - it's there, it works, it's easy.

But now that I have that list above, I smell a project coming on.  Break
out the 63/37...  no, wait - resist!  [photo resist? okay...]
