Don't be stuck behind the projection PC during your services.

Having been behind the projection PC during a service - I felt disconnected, like I wasn't even taking part. The idea was born, create a solution that makes the job of controlling the media for a service less isolating, without limiting control. Using any mobile device, you can control the service - even from the front seat!
You can roam wherever you have wifi signal on the same network as the projection PC; test your limits!
Any device with a web browser can be used as the remote controller, including laptops, tablets, and mobiles.
