Abacus iPhone Case: For When the Calculator App Crashes
While Apple definitely made it easier to access the calculator in iOS7, you still might find yourself without a way to do math on your smartphone. Maybe the battery ran out, or maybe you’ve found a way to make the Calculator app crash. Either way, you need a “Plan B” for your maths. I present the solution to this challenging equation – the Abacus iPhone case.
This 3D printed case designed by Joaquin Baldwin provides a fully-functional abacus on the back of your iPhone, letting you work math problems without even slightly draining your battery. And as an added bonus, you’ll get tiny Apple logos in place of traditional abacus beads.
