Nice! I see room for expansion!

I made the lamest thing ever.

Mine is a bit big, but truly amazing, even if I do say so myself. This is my first doodle, so yeah.

"Controls":
- Mouse hold: reverts the magnetic force (repulses balls).
- Enter: Toggles economic mode: increases FPS (at least for me)
- Space bar: doubles the magnetic field and the magnetic force
- "up", "w" or "+": increases simulation speed (up to 5x faster)
- "down", "s" or "-": decreases simulation speed (up to 5x slower)

EDIT: Added a few more things to this doodle:
- Fields are affected by "economic mode"

And added more "controls":
- "r": Restarts the doodle
- "f": Creates a copy of the force field of your mouse (position, force, field)
- "c": Clears all the copies of force fields you made

The new code:

#3: Fish Tank

Use mousewheel up and down to change quality/width of the lightbeams. It looks best at width 1, but bigger beams work better with some fish swimming under most beams and some swim over most beams.

Wow, these things are becoming more advanced than I expected. They all look really cool! I kinda stopped doing the daily thing. I'm out of ideas for now.

[HugoBDesigner]

Not sure if you guys liked my last doodle, but this one, even though doesn't look really advanced, was pretty hard to make (for me).

"Controls":
Space bar: switches between inwards and outwards circle
"R": Sets random colors for the circles and background
"I": Switches the colors of the circle/backgrounds
"-": Decreases the mouse radius
"=": Increases the mouse radius
Enter: Changes the drawing mode
