During NASA’s Mercury project (1958-1963) teletype systems were used for mission critical communications between Goddard Space Flight Center and remote tracking stations and was comprised of over 100,000 miles of teletype lines!
These planetary pieces show actual punched holes (words in digital form) in teletype tape overlaying an abstract planetary body. So cool!

EACH DotDot is available in 3 different sizes 18", 23" and 30" diameter. The cleat bracket holds the piece off the wall about 1/4". If you want to create a grouping that overlaps I can work with you to make brackets that allow for this overlap.

Pricing by size: 18" $795; 23" $995; 30" $1295
