Thanks, I know for one thing, that if these don't work, then I will put them into a handheld fan and use is to cool down when we go camping in during the summer.
There were some plans for the fans on the website (in fact, here they are)

However, they were not very clear so I ended up making the fans spontaneously, that is without much planning and a lot of luck. They were going to be layed down horizintaly at first but then I decided (I don't know why) that it would be better to stand them up and had to change the duct design halfway throught the process. The first one too about three hours - the second took one. Some may think that this is a bad strategy for building and that everything should be planned out, but I just like to build and then see how everything fits together. It is just how I design things.

Oh, and by the way, taking these pictures sure is a pita sometimes... I may have to limit them as I barely have time to grab a camera in between glueing, cutting, and messing up.
