When I was younger, I often had dreams when I was asleep in which I raised my arms and flew effortlessly across the landscape.  I had the opportunity to have a similar experience while awake when I was in Taiwan earlier this year.  I am fairly frequent visitor to Taiwan [see ‘‘Crash’ in Taipei: an engineer’s travelogue‘ on November 19th, 2014 and ‘Citizens of the world‘ on November 27th, 2019].  I often go with colleagues from the UK who have not been before and almost without fail we visit the amazing National Palace Museum.  On my last visit in January [see: ‘Ancient standards‘ on January 29th, 2020] there was an exciting blend of art and technology in an exhibit that allowed the visitor to fly through the landscape of a painting.  I stood in front of a projection of the picture on a large screen and lifted my arms for a moment to allow the computer system to register my position before starting to fly into the picture, tilting left or right to turn, and lowering and raising my arms to slow down or speed up.  Although there was no mask or headphones to wear, the experience was absorbing and realistic.  You can watch me flying with my ‘jetpack’ in this video.
