I made a couple of designs for the Hoverbike: The Airfoil and The Spinning Prop. The Airfoil is actually a cross-section through the same propeller but at different distances from propeller’s centre. The designs and t-shirts come in various colours (chosen by Chris Malloy and myself) and sizes, both for women and men. Together with other designs, they can be bought here. Oh, the image boards were made by Chris.
