I wanted to build it into an red analog telephone. The phone would ring and you would hear a message from various government/military types.
As tensions rise, the phone rings more often, possibly multiple lines light up forcing you to catch/miss vital information or opportunities.
Inevitably, things go pear-shaped and you try to (prevent?) a first strike/retaliatory strike.
Truthfully, I don’t have the skills to build the device, but plotting out the narrative, writing the dialogue would be fun.
