Lobby to get Simone Giertz to come to Vex Worlds this coming year. (Maybe if she agreed to a PG-filter) She encompasses the build your robots to do weird things - that may not always work well, but always have high comedic value. Just what aspiring roboteers need - inspiration yet approachable to make cool crazy robots.
But maybe the next president? If Hilary wins I could totally imagine her going on and on about STEM careers for women at worlds. Not sure if Trump would do the same, but I think he would approve of Starstruck lol
How about just the whole Mythbusters crew? If they really wanted, they might be able to run an episode at Worlds, which would be great publicity for Vex.
