I love the concept and I'd be willing to pay for the high price no questions asked if the device included all the backend needed to display images. Given the high price I'd expect this to be self sufficient. I truly hope a soon to come interaction of the product will include such a feature, so that setting the target URL by connecting to the device (via localhost or similar) will make this work.

My best scenario would be: - plug it the first time, a new wifi network is made available - connect to the wifi and visit the locally hosted config page, which includes the wifi network to connect to and the URL to fetch - the screen restarts and connects to the wifi and, if internet works, fetches the URL - at any time, the screen can be configured if connected to the same wifi network (might require an app) - a physical button resets the screen to the factory config
