How do you tweet in Morse code? Using Arduino and antique signal lamps, it turns out.
Thanks to students from the Copenhagen Institute of Interaction Design, you can now see what "I just washed my face and brushed my teeth. #Monday" looks like when expressed via old maritime communications technology.
The students' #CPHsignals "Morse code light signal installation" transmits signals between two Copenhagen, Denmark, neighborhoods, Nyhavn and Chavn. Visitors can tweet messages using iPads attached to antique signal lamps on either side of the harbor or from anywhere using a @reply to @signals_nyhavn and @signals_CHavn.
