Journey to the Center of a Triangle

In 1977, Bruce and Katharine Corn­well used a Tek­tron­ics 4051 Graph­ics Ter­mi­nal to cre­ate ani­mat­ed short films that demys­ti­fy geom­e­try. The films have now reemerged on the Inter­net Archive. Jour­ney to the Cen­ter of a Tri­an­gle appears above. You can also watch Con­gru­ent Tri­an­gles, which fea­tures the mem­o­rable ‘Bach meets Third Stream Jazz’ musi­cal score. Enjoy.
