Just a thought to make one.

Find a PIC with enough I/Os. 1 input and 16? outputs.

Code something like..

If PIN_IN is high then
count = count +1
If count = 1 then high LED1
If count = 2 then high LED2
so on and so on...
If count = 17 then count = 0
Start over.

Every time PIN_IN goes high the counter increases.
