Functional prototypes of both hardware and/or software (web and/or mobile). I used to help companies like theme parks design concepts and build prototypes that they could use to get sponsors for their parks. As well as large corporations that needed wuick prototypes of apps or games that they needed to fundraise to fund the full product development process. I would basically help them up to the internal or externL fundraising pitches. Won awards for my work. Im just sick of client work and would love to find a way that I could use my skills in a more independent way.
