With a project called Tinycade, graduate student Peter Gyory has set out to recreate that arcade parlor experience from childhood—entirely out of junk.

All you need to make your own Tinycade game is some cardboard, a smartphone, two small mirrors, rubber bands, and toothpicks.

This DIY cardboard playhouse was created especially with small spaces in mind: when the kids tire of it, the playhouse collapses flat for easy storage!

In addition to cardboard, a hot glue gun, a couple of electric motors, and a bunch of wire, you’ll also need hacking skills that rival MacGyver to build your own Mario game on the cheap.

A creative fan designs an arcade Mario Kart machine out of cardboard, along with a drivable kart from the beloved Nintendo series.
