HTML is incredible and powerful. HTML is a mess. Marcin, a user experience designer at Google, will talk about the experience working on interactive doodles like Pac-Man, Jules Verne and Les Paul. How do we put together things that will be seen by hundreds millions of people? What did we get right? What did we learn the hard way? What rules were broken and what contraptions put together? (Oh, and make sure to bring your phones!)

Marcin Wichary has been coding HTML by hand since 1994 and still finds it fascinating today as a senior user experience designer and developer at Google.
