For those who aren't aware, online Calvinball is available if any users have a desire to play Calvinball!
I found this website because I was desperate to play some form of Calvinball. It doesn't receive much activity, but if individuals like you come to play we can make this potentially brilliant website more popular! There have been a lot of posts there over the years, and people have been giving up because nothing ever happens. It's not the same as real Calvinball, as you have to type out everything you do, but it would be really fun if people played it..
So let's make this site hit the top of the "Calvinball" Google results and play the game!
Note: I am not the creator of the website. You will see me playing as "L".
