This circuit creates the infamous 'Knightrider' running lights Transistor outputs may be added to run relays etc instead of LEDs, if any outputs aren't used link the first unused output to RST terminal, eg if only 3 outputs are used then link output 3 to RST terminal.
Photo showing five of the outputs used to drive transistors which trigger relays, a fine adjustment variable resistor has been added to allow the speed to be adjusted.
