[PD] multipoint touchscreen

[Hans-Christoph Steiner]

A friend of mine was working closely with the Tactex company to try to  
get them to make a useful musical controller using Tactex.  Ultimately,  
they decided that they didn't want to spend the money to do what needed  
to done to make Tactex a good musical controller.  Its got a couple of  
key problems: very low refresh rate (i.e. latency), something like 50  
Hz; and it can't detect two points of pressure closer than about 2cm.

He wrote a paper about the instrument he built using Tactex:
