With another Rice student and ICPC contestant, Jeff Erickson, he wrote TopDraw, a black-and-white bitmap drawing program that was purchased by Beagle Bros and became BeagleDraw.
StyleWare was purchased by Claris,[6] and with Scott Holdaway, Hearn became one of the two original developers of ClarisWorks, a popular integrated office suite for Apple Macintosh computers.
[4] He later became a doctoral student of Erik Demaine at the Massachusetts Institute of Technology, co-advised by Gerald Jay Sussman.
[7] His 2006 dissertation invented nondeterministic constraint logic and used it to characterize the computational complexity of many games, puzzles, and reconfiguration problems.
