Indoor radio-controlled helicopters, which I have been featuring in Technopolis from time to time for a couple of years, continue to evolve. This one will display a message in little red LED lights as it hovers around friends and family. It can fly up and down for about six minutes, by which time the joke might just have worn off. Messages are limited to seven characters, which even in the age of Twitter is a bit stiff, being too brief for “I love you”, although just long enough for “Go away”.
