I just finished the Mega Menorah and I have to say it is an amazing piece of quality, design, and programming! The only change I made was to include an IC socket in case there was a future SW revision. The display varieties seem almost endless! Those LEDs are something I have never seen before (I was wondering how you could get so much functionality with only 3 wires between the base and Menorah boards). Well done!
I checked out the link you sent (thank you) and was wondering if there was consideration for an even larger Menorah using the jumbo LEDs?
