Probably the best way to share it is to save out the deck as html and upload it somewhere - neocities is a good option for simple web hosting if you don't otherwise have something available.
In the meantime, if anyone wants to see this in action, just paste the code into the card script and make a canvas on screen named "canvas".
It's a cool effect that I can see people getting some use of - it could be a fun challenge to turn it into a module so it can be more easily reused, as described in the modules section of the doco. Or maybe as a contraption?
