People might find this paper interesting -> https://www.researchgate.net/publication/354364068_Fifty_Nifty_Variations_of_Two-Transistor_Circuits_A_tribute_to_the_versatility_of_MOSFETs -- Would love to see all of them done on SKY130!

@User Thanks for posting--I think it would be cool to create a 'tribute' chip that had several iterations of each of the 50 transistor combinations. I'm planning to reach out to the authors to see if they'd object--and if not, if they'd like to collaborate
