Core 77 is a website by and for mostly industrial designers but mow covers multiple aspects of design.
They covered Orp in this first article during the Kickstarter campaign.
Orp Smart Horn
Remorp
Also, I did not expect a reply from the designer! So let me say how pleased I am with your product. In fact this morning I heard another cyclist using theirs behind me and we had a nice chat at the red light about how awesome Orps are. The remote is just genius, and mine is cute as can be with its Tom Selleck ‘stache.
