The Big Red Box is a piece of experiential technology that could be described as an audio guest book.

At weddings or any type of events, guests are able to leave you voicemails via telephone, inside a beautifully handcrafted replica of the iconic British red telephone box.

Shortly after your event, you receive a little red box, which contains all of the answer phone messages from your guests stored inside. 

The installation is using a concealed notebook, an Arduino and some bespoke software to run and has been showcased at many wedding fairs in the UK.

I have been acting as a CTO for The Big Red Box. More information can be found here: https://www.thebigredbox.co/
