Sometimes it’s fun to waste parts in the desire to learn how something works. I haven't ever connected more than one shift register together before. I went to my parts bins but was defeated to find I only had one shift register so, the bench testing fun will have to wait. Below is a simple circuit using two 555 timers as a clock and "data" input. In real life I was going to use one of my favorites the LM556 a dual 555 time on a single integrated circuit (IC). As for the shift register the IC of choice was the 74HC595.
Once built in the simulator I became inspired to try and out the LEDs in a fashion to use as one of those 3X3X3 LED matrixes. Make it like random-ish static cube, I'll have to play with the design a little more.
