Mojipic Display

I backed a mojipic from an indiegogo-campaign:
Mojipic

It’s a LED-Display battery or cable powered.
It’s very bright - even at sunlight.

The device is controllable with an app via bluetooth and can display images, animations or text.

It would be great to have such a device with an openHAB binding.
There’s no open API and I’m playing around with a tasker-proxy to evaluate some examples - but that’s quite quirky…

Do you know similar devices or do you think there are ways to control it with the bluetooth with an rasperry by simulating app commands?
