I know that a PIC could be programemd to do this.

Yes a PIC.

You're not allowed to say "use a pic" without providing a schematic
and full code listing.

OK, use an '8051' then. 63 cents indicative price for this one. I don't
do PIC code but I could ask my nephew to do that !.

My first thought was a 3-bit shift register.

Far too many parts !

Note that the OP was aware that a PIC could be used, but asked for
"the simplest collection of logic chips" which would do the job.

Oh, OK. A counter with auto-reset is the answer then.
