In 2015 an entrepreneur approached GHE to develop a prototype for one of their ideas.  We cannot divulge the details of the project as the idea is not yet fully protected but we were able to work with the client to create a simple working system that effectively demonstrates their concept to potential investors. The prototype involved a flexible full-colour LED display driven by a microcontroller and a good quality sound system.  Some 3-D printed parts completed the prototype and the customer was very pleased with the result.
