There are 11 different cloud values that are the same for everybody which are from 0 - 10 You can set the cloud value to mean something to make the cat meow, or to make a sprite move. They go a little too fast, but don't worry, because it never skips any values.
Fun fact: This doesn't contain any cloud variables. That's right, NONE! But how was I able to make the value the exact same thing for everybody? I did this by using the 'days since 2000' block which is always the same for everybody, like cloud variables and unlike regular variables. Meaning that even though that they can't use cloud variables, New Scratchers or even Guests can use this system! This can be easily done with the 'current second' block, but it would be a bit too slow.
