There was an online demo, but with the end of the project this summer 
the university deleted it.

If you are seriously interested I could send you source and the project 
report. I just don't want to make it fully public, because there might 
be copyright issues with the University of York.

Halipeto only appeared in the middle of the project, and hence wasn't 
The JavaScript is not just annoying for people like me who turn it off 
by default. In WASH it mostly serves for checking input fields. For this 
application there is not much need for checking input fields and the way 
in which WASH indicates errors in input is in my opinion not very clear 
and helpful.
