Magma Studio is a fun little web app. If you've got a browser, you've got a drawing app! Mostly. If you're using MacOS Safari, you get no tablet support. If you're using iOS Safari, you do get tablet support but no paste function. Both make me chuckle a bit. But overall, it's fun to play with. Sure, it could use some more functions in there, but I think it's a solid base app to build on. And you have draw with 30 friends at the same time! Big time art jam! Reminds me of the old oekaki days in the 90s.
So check it out. This is not sponsored, but I had fun with it and I think you will, too!
