I designed this key using the alien language created for the show, and with the knowledge that it would need to somehow morph into a key in order to detonate a bomb.

This one was particularly fun  because we were able to print the key in the stages of morphing, assisting with the VFX in post, and allowing the actor to actually hold and use a physical key in a lock.

 

 

Below you can see the key before it was painted to look like metal and rust and one of my hand drawn designs.

Here are screen shots of the key in action.
