Awesome!

WTF thats amazing!!!
no scripting!
no nothing
I see tracers and things
how you make it go up and down as needed with no scripting?

diffrent calishun for each ball on the chain

Brilliant! 10.

It's spelled collision

Amazing, just amazing, amazingly amazing 11/10

good work

keep it up!

10/10

hoooolllllyyyy shiiiiit!! awesome

...

Very good work! 10/10

Interesting mechanism...

THAT is Awesome!

It's programmable and multiple different colors! AMAZING!

omg!!

must have taken ages to programme

how do you make it say different things?

Actually, programming isn't that bad.

Each set of light-colored balls on the chain is a letter. The first ball (on the left when the ball is being read) corresponds to the first column, the second to the second, so-forth.

If a ball collides on A (but not no self collision), the corresponding column will have a pixel lit up at the top. Collision G means the bottom row. If all seven collision layers are checked, it will print a vertical line.

A ball that collides on any one layer, collides with water, and with no self collision will print a blank column.

For example, if you wanted to print a question mark:
1. Get an idea in your head of what a question mark looks like.
2. Think of what it might look like if it were in a display with 5 by 7 pixels.
3. Find which set of light-colored balls will be our question mark. Find which of these is the first one.
4. Uncheck the No Self Collision box for all five.
5. We'll probably want the top to be rounded, so uncheck collision A on the first and last circles, leaving it on for the middle three.
6. We want both sides to be vertical, so check collision B and C on the first and last circles.
7. On the right side, we want it to curve back in toward the middle, so check collision D on the fourth circle and collision E on the fifth circle.
8. Finally, we want the dot to be centered on the bottom, to check collision G on the third circle.

Test it. It should look something like this:
__________
__$$$$$$__
$$______$$
$$______$$
­______$$__
____$$____
__________
____$$____

Simpl­e really.

BEST PRINTTER EVER even better then the one on the "feutered page"
