This is really cool! You should contact the Made in America show (The Discover Channel???) and see if they'll do a segment on the PSP kits. It would be good advertizing!

One thought - I'm not the slowest reader, but I did have problems reading slides with longer text before it moved on to the next slide. A slightly longer time between slides would be appreciated. If there is any way to allow only the long-text slides to go longer that would be best.
