Meet the Virtuali-Tee: a cool t-shirt that comes to life through your iOS or Android smartphone/tablet. It lets you view human organs in an interactive fashion and from the inside. This educational t-shirt is compatible with VR headsets as well.
The Virtuali-Tee looks like a regular t-shirt but provides your kids with an interactive learning experience when viewed through a phone. The app is for free. More information is available on Kickstarter.
