The drawback of having a cast this cool looking? No one is going to be able to sign on it. But who cares! You want those broken bones to heal. And heal fast! Deniz Karasahin designed a custom cast that comes with an ultrasound device to speed up bone healing.

Karasahin's Osteoid is, for now a design concept. He won the 2014 Golden A'Design Award in the 3D printed forms and product design category. He also uses some science to his design. Based on sound science, using a low-intensity pulsed ultrasound (LIPUS) has been found to reduce bone healing time by nearly 40% in a 20 minute treatment a day.

This won't be possible with old school plaster types. But a 3D printed cast? No problem. [A'Design Award via DamnGeeky]
