Près de 12 ans après être arrivé sur Mars, le rover Curiosity continue de nous émerveiller par ses découvertes !

I'm giving a talk for the Oregon Museum of Science and Industry (OMSI) on June 18th! OMSI has a lecture series called Science Pub and I'll be talking about science in video games, both in the making of them and in the games themselves. Should be a lot of fun! If you're in the Portland area during that time, come join me! It'll be at the McMenamins Kennedy School Theater on June 18 at 7pm.
