Prof Jon T Njardarson gave a talk at my university a few years ago. These talks were given every week during term by various professors from around the world. Njardarson stood out because he was young, enthusiastic and talking about total synthesis and the new chemistry that it spawns. Also, one of my favourite lecturers went to university with him back in Iceland:
"Ooops...dropped my sodium"
Anyway, apart from his cool posters ,JTN has an app called Chemistry by Design. It's over 400 total syntheses in an interactive, flashcard format. If I was studying chemistry full time I might while away a few hours playing around with this. Right now it would be masochistic!
