So, this is my attempt on implementing Game of Life. It's not great, but at least looks quite good (because GRADIENTS!).

Things to try:

toad

glider
■ ■ ■
■ □ □
□ ■ □

crocodile
□ □ ■ □ □ □ □ ■ □ □
■ ■ □ ■ ■ ■ ■ □ ■ ■
□ □ ■ □ □ □ □ ■ □ □

this might not have a name but becomes huge and pretty
□ ■ □
■ ■ ■
■ □ ■

this eventually spawns 12 gliders

Have fun!
