you can try using CD4093 (quad 2 input NAND schmitt trigger) a source for clock pulse and a CD4017 (decade counter/divider) to drive your LEDs. it has 10 outputs.
or if you want something a bit complicated try using the PIC16F84A. it can also directly drive 8 LEDs.
there are lots of circuits of this kind in the web. a little patience will give you results.
