Hi Chris.

In my opinion, no single logic device will be able to handle it, or the
design effort isn't worth it (even using shift registers + initialization
logic around can lead to unexpected results and be very big).
The two obvious solutions would be :
- either an old EPROM (1 for 8 LED outputs) you program with the LED
sequence and you scan with a counter
- or a microcontroller with the program to output the sequence on its output
ports.

OK?

The microcontroller sounds like the way to go to me. I haven't done any
electronics in years though. I am a programmer by profession now so I don't
think I will have a hard time learning to program the microcontroller but I have
now idea where to look to find one that is reasonably cheap and preferably
rather small. I'm thinking that I will need some external method of increasing
the current abilities for the version that lights 10 LEDs at once, is there a
pre packaged unit that would take signal to turn on a high current load? Kind
of like a solid state version of a relay board with a lot of inputs and outputs.
