One technique I've used is to press a smooth drinking glass against
the strings before striking the keys. Strike, then slide the glass.
A similar technique is used in George Crumb's music.

Somewhat more germaine to the newsgroup, using samplers one can add
vibrato with LFO/Rand generators (even in real time if your hardware
is up to it !). Also, a ring modulator can be set to give beat frequencies
in real time, as well as other tuneable feedback techniques.
