This week on Maker Update, a Jedi-worthy lightsaber, Kickstarter’s test print, an iFixit giveaway, a musical dodecahedron, sound bending, disc shooting, MIDI motors, and stringy plotters.

The annual Game Developers Conference in San Francisco is a wonderfully outrageous, high tech fantasy land where corporations like Microsoft, Facebook, Sony and Google, hold court with their latest zombie-blasting simulators and VR headsets. But it has a secret.

Off in the back (technically in a whole separate building), away from the buzz and hustle of the main show floor, is a small cluster of 20 curated, one-of-a-kind games under a banner labeled “alt.ctrl”. Here, the creators of these games encourage people to come over and play their project. They call themselves Developers, but I see them as Makers like myself. People who take their fun from mixing equal parts Art and Engineering.
