Bands pull now with a constant strength and a specified target distance.
Maybe extra types could be usefull:
- a band that does not pull when within a specified range, but does outside that range
- a band that pulls harder when the target distance is greater, something like
F = -kx or even F = -kx^2
- a band that is totally rigid, preserves the specified distance

Can you post a link to the overview of band suggestions?
Another idea is to allow bands with F = k x instead of F = -k x:
Since F = -dU/dx, F = -k x gives potential energy U = (k x^2)/2
(a potential well, like for the attraction of + and - charges).
This is how Foldit bands work at present, obeying Hooke's Law
for springs. To test this, run DoBandsObeyHookesLaw1 from

Meanwhile, F = k x gives potential energy U = -(k x^2)/2
(a peak in potential, like for the repulsion of two + charges).
As requested: http://fold.it/portal/node/992891 is an overview of all band suggestions.
Thanks, Timo
The rigid band is a must for me. I often want to pull or push a small distance, but with great force. At least, have a marker on the band length slider that indicates the current distance between the objects being connected, so that the player can make the band just larger or just smaller than the current distance.
