Have you ever done(or heard about) sprites?

For those of you who don’t know what they are,they are basically a 64x64 sheet where you can basically make a 2D model or animation,kinda like the BW sprites,that are usually ported into games and such.

Now,while I did make some of them a few minutes ago,I’d like to say that I’m not planning on making a game. I have little to no knowledge about programming,so I only make these sprites for fun.
