Press the green flag button and enjoy the show! It'll take a second or two to load, so don't worry if the project doesn't start immediately. Pressing the fullscreen button after starting it seems to cause some issues, so make sure the screen is the size you want it before clicking the green flag.
This is a free fan project. I'm not affiliated with The Big O or anyone who worked on it in any way. Sometime in June of 2019 I was thinking about the intro of the show The Big O, and realized that since it mostly just involves images of characters gliding around the screen it would be pretty simple to recreate in Scratch. Two years later, after a few phases of working on it lots and then not touching it for a while, I finished it! It was fun to make but I don't recommend doing something like this unless you're very patient :^) I made almost all of the assets by tracing over still images from the intro in Scratch's vector editor, except for the corkboard and tie dye-looking backgrounds which I made in GIMP, the lava-looking background which is just an unmodified still image from the intro, and the newspaper backgrounds which were compiled from many still images from the intro.
