After the huge amount of replys in this topic i for all ask to Scawen to develop L.F.S.
Live for Shit.
A new marvelous simulator that reproduces all types of Wc, germans american, european, third world holes..., and of course of metabolism.
Demo version features only american wc's and slow metabolism.
It will be possible to have an outgauge application that flushes your connected wc in real time.
Also it's possible to skin your unique wc and use it on line.
