NFT artists: if you've created an NFT and/or NFT collection, can you link examples here? 

Ideally OpenSea links please!

Sure! I dropped this infrared collection 1.5 yr ago, one of my first collections on ETH

Then moved to KnownOrigin and Makersplace.

KnownOrigin is nice and I'm using more for editions. It allows me to set special price for current collectors of pieces of mine for a limited time, so I created a very low cost piece on 250 editions for 0.002 $ETH where I call "Early Access Pass".

What are KnownOrigin and Makersplace like?
