The poster was made with the idea that it should guide us while presenting our ideas in a lecture like presentation, similar to a Power Presentation. But we did not get that opportunity.
Few people took the trouble to read it. It only served us when we explained to visitors that it really had been used in Ghana, that it really was Julia that took the Hy2U to its first successful application.
The little illustrations in the lower right corner were very helpful. Without them we would not have been able to explain about the BathroomBox and the BathroomToiletUnit.
What the Poster also did was to provide us with a free congress week for five of us!
