Sorry for the late reply. I appreciate the interest. Here's a bunch of video links:

2nd (theoretically) Lightning Powered Arcade game (the LN integration was not quite complete) - the all custom Magical Crypto Friends Arcade Game, delivered as a surprise for Samson, Charlie, Whale Panda and Ricardo to the MCF Conference in NYC in 2019:

I have been working on a MCF Arcade Game v2 since 2020. The rona put a spanner in the works, but the game is functioning, contains many more Bitcoin (and crypto) personalities a few new features and new game levels (in progress). It also currently demonstrates LNURL-withdrawal so those who manage to complete the game can collect a reward. At some point I hope to finish the v2 and put it into a full size arcade cabinet. I'm looking for interest and hopefully a boost of motivation. :)

Thanks again for your interest and sorry for the delay.

I just found an earlier video from 2018 at the Fulmo #LightningHackDay NYC, where I present my idea and progress trying to solve the static QR code problem that existed when LN was first introduced, and has since been very thoughtfully addressed, and then some, by fiatjaf with his LNURL project. This hackday was where I met Ben Arc, of later lnbits fame, among many other impactful projects he's produced, and we helped each other with our respective ideas.

So this hackday truly kicked off the whole process. I hope some of this motivates people to get involved. I knew very little about lightning, beyond the basic concepts, when I attended the event. There were many amazing and enthusiastic people there. It was well worth my time and hopefully my little projects helped get other people to see where this could all lead and maybe to get motivated to contribute as well.
