Be sure to scroll down to see the advanced foil effects on cards, the top card is a very basic example.

some people just mastered their domain. i pray i get this good in my area of expertise: elliptic curves. lol im researching curves on random math sites, and learning different implementation tricks (like the subtle diff in MSB and LSB implementations of the double and add algorithm* or that sometimes you can find the weirdest endomorphisms on non-binary Koblitz curves (they're not documented AFAIK and Koblitz the OG is too old to be chasing 1-bit, 2-bit endomorphisms)

This was me in awe of the pokemon card CSS lol. It appears to have been done before AI and this makes it even more impressive tbh.

*The diff is in MSB->LSB the generator remains constant while in LSB->MSB to the generator doubles. Either way, you always know the value of the generator at every bit. I think this is a vulnerability but I just can't find out how.
