H.A.T. A Fringe Festival Collaboration

This year DIY Planetarium partnered with the 4 actors in Fort Collins to present "H.A.T.", a tragic comedy in 3 acts. H.A.T. was a planetarium/acting hybrid show, in which audience members took turns wearing a kichen collander that visualized their thoughts on the dome. The video above contains some animations from the show. Thanks to Luke, Kati, Jacqui, Nick, Judd, and Ben for making this performance possible. #FortCollinsFringeFest2015
