Another possibility is Science on a Sphere (projected on the sphere rather than an active display):
I see they have one in at the McWane Science Center in Birmingham, AL -- perhaps a few hours away, by car, from you in Huntsville.
You might need a slightly bigger office to fit this one but, the globe that you want is hanging in the Tokyo Science museum: http://tokyotek.com/geo-cosmos-gigantic-globe-oled-display-video/
Watching realtime weather patterns on it and day and night images is pretty cool.
On the perhaps slightly positive side, there is a Science on a Sphere system at McWane Science Center in Birmingham, Alabama (http://www.mcwane.org/ ). This might be sufficiently close to you that you could go and see what future generations might have in a smaller and less expensive form.
Also, my pessimistic view need not correspond to reality.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
