Yesterday, in a local TV channel here in Colombia (City TV) a very well known Colombian rock band was interviewed on the talk show "Radio City". The name of the band is "Estados Alterados" and it's thirty years old. Its lead singer, Fernando Sierra AKA Elvis, is also a teacher of paper engineering at a university! At some point during the show he taught two of the hosts how to make the paper helicopter. The one where you use a long rectangle and you make three different cuts in order to make them.
Here's a an old video of one of its most popular songs: https://www.youtube.com/watch?v=zhL57kuTflQ And here's a picture of one of his works in paper engineering: https://www.flickr.com/photos/elelvis/15086811700/ I was happily surprised *: )*
