Invention Cycle
CREATE: Come up with a bone-chilling idea to unleash on an unsuspecting world.
Grab some Bits and a pile of Halloween props. Tinker until your idea comes aallliiiiiivvvveeeeee.

PLAY: Recruit some ghosts and ghouls to test your magical contraption or costume.
How do you want them to react? What kind of feedback do you want from them?

REMIX: Use the feedback you received to make changes to your design.
Maybe you want to add sound or make it move. Or perhaps you decide to change your idea completely - it’s totally ok! Just be sure to test it again before sharing. :o)

SHARE: Make a video and share your masterpiece.
Create a walk-through of your invention or film a scene featuring your gadget. To submit to the challenge, upload your invention using the Invention Editor and click on "Hack Halloween".
