If all you are really looking for is to cook some paint, why don't you 
simply use some small resistors instead of diodes.
A PIC will source/sink 25mA, so...
5V / 25mA = 200ohms.
5V x 5V / 200ohms = 1/8watt.

Just use 200ohm resistors smaller than 1/8watt, so now you have a penny 
each for hot resistors.

or

If you want to have fun, you can silkscreen that resistive paint used to 
repair the rear window defrosters on cars. Then silkscreen your 
permachange paint on the silkscreened resistors.

Just use a bit of imagination and Have fun.
