Unusual media: Nnedi Okorafor's "From the Lost Diary of TreeFrog7"

While the story itself (from Clarkesworld, May 2009) is unremarkable (a jungle adventure with strange creatures & "CPU plants"), it's noteworthy because of unusual presentation - a story clearly meant for online world rather than for paper world: it has embedded links with additional text behind them. While a paper version could conceivably put this text in footnotes, they would be far too long - it works only because of online "hidden behind hyperlink" layout.
