I dont understand why these people are putting such a high valuation for a project like this.
It could be done with simple components for relatively cheap...
The problem is getting the data to the machine. Would BluTooth be an option? I can make an iphone/android app that will allow you to control the device. You could even have it display alt coin prices as well.
The issue is the goal is to keep it to where it doesn't need a device like a phone to handle it. It would just be a ticker that uses like your router and automatically updates or something.
