Very cool. Could you add base64 encoding to the query part so that it doesn’t hint at what the screen will say from the link text. Kind of gives the joke away sometimes.

Might need to be careful: there's actually a URL-safe variant of base64 [0] that might be better, although the problematic + and / characters are probably not actually problematic within a fragment (+ only means space within the query, and / only means folder within a path and if a server wants it to) in which case standard base64 could be fine.

The example with the coffee bean background image already uses base64 for the image data, so I guess that would get double-encoded.
