Nora Young’s Spark will run a program on “Addiction by Design” tomorrow, featuring interviews with Natasha Dow Schull (who has written some great stuff about the design of video gambling) and a very scratchy-sounding me. (I was in the process of getting over my month-long cold, so my voice was a couple octaves lower than normal.) Schull is worth listening to, at least. [mp3]

This sample has a nice Candy Crush illustration.
