an alternative to the putty would be a reconfigurable skeleton with an elastic skin, less messy but more unknown and harder to fix

ideally I'd have something like a small shoggoth that could reconfigure itself but I don't know of anything that would allow it to do that

hmm trying to think of a workflow say you have a 3d object on a screen and a bit of putty in front of you software matches nodules to mesh

you knead it a bit until the thing on the screen has the right shape, select/deselect a few nodules for fine tuning

then you "detach", rotate your workpiece on the screen, focus another area, repeat until content

another thing you could do is explore complex multiparameter spaces, push nodules around until the thing purrs

now if the putty could harden/soften locally on command, it could signal force fields even better than with vibration

do not think of lewd do not think of lewd ah dammit yeah I suppose the porn and telesex market would be onto it big time
