Xiao Hu,

I took latin for three or four years in high school and would love to do Popup Latin at some point. Of course, two problems are that we never actually learned how to pronounce the language and I can't imagine the market being big enough to make it really sustainable.

But I hope we can do it eventually. Roman history is fascinating and latin is a beautiful language (I really liked reading Catullus). And latin's convoluted morphology would also make it perfect for the popup approach (ablative, accusative, etc.), while Classical Greek and Hebrew would be interesting to do as well.

I've just registered all three domains (popuplatin.com, popupgreek.com and popuphebrew.com) to add to our somewhat bulky list of dreams.
