Anyone speak Hieroglyph?

I've been watching Eddie Izzard's show "Stripped" on the BBC iPlayer, and found myself distracted by the backdrop (not an easy feat, given it's Eddie Izzard in front of said backdrop). The reason for the distraction: Language, specifically, languages I can't read. There are Egyptian hieroglyphs, there is writing in Devanāgarī and in Cuneiform.
It annoys and intrigues me that I have no idea what it says. Or if it says anything.
