With only a nod and a wink to Newtonian physics, I bring you... pull.

Click and hold in the space to form your own instant pseudogravity well. The motion is damped by sortafriction.
The particle outlines vary in hue and saturation with their velocity.
Have fun.

kewlies. what's happening with the particles being shot off faster than when they were pulled in?

the attraction is inversely propotional to the distance from the attraction point, so you can get a real slingshot effect if the particles stray really close. There may also be a math error there, either in the floating point calculations, or in my code. I think I'll plead artistic license.

In most gravity-based things, it's nice to make gravity 'not work' if the particle is within X units of the attractor. Stops the speed approaching infinity (and any potential divide by zero errors).
