mysterious glowing object(s) #3

"Now you can build futuristic cities... with LIGHT." Astrolite® was a set of clear plastic shapes and connectors that could be constructed over a multicolored glowing base. With it you could build self-illuminated Jetsons-like structures, glowing robots, space stations, etc. Astrolite pushed beyond the boundaries of "child's toys" in terms of its visual sophistication. Manufactured by Hasbro in 1969, these can frequently found on Ebay; since the only electrical element was a 40 watt lightbulb, most of them are still in fine working order.
