Not necessarily gaming related, but I found this video from one of my educational links. It’s of Prague’s Astronomical clock built in 1410. On its face was displayed an amazing light show- Not your typical lasers, but this was simply astounding. The wonders of technology continue to amaze me as well as the skill and artizanship of those working centuries before.
Those of you heavily into role-playing can use this as a great location for some adventuring, or some Cthulu-esque horror story.
