The 10Fs only have 3 output pins - yes, you can charlieplex, but that only
gives you 6 LEDs - only 3 x bi-colour or 2 x tri-colour.  Can still make a
nice little display with that, though.

Software PWM for multiple LEDs would be quite a challenge with only 1
timer and no interrupts.  Possible, of course, but certainly challenging.
