0603 cap = 1 cent
0603 led = 7 cents

Even the venerable 555 is too expensive in the small sizes appropriate
to this project (about $0.60).

Now, if you can think of a circuit that uses a flip flop and some
inverters, plus low-valued caps (even resistors cost 3x what caps
cost), that might be feasible.

(ok, so it's more than just a *soldering* challenge ;)
