AJ Hackett Macau commissioned Prism Productions to produce a short narrative description of what it's like to climb the Macau Tower - the world's highest urban climb.
The summit of Macau Tower is 338 meters and to get there requires climbing 100 meters up vertical ladders. Even the team at AJ Hackett rate this as one of the scariest adrenalin-rushing activities they have - so you can imagine the look on our photographer's face as he lugged his Canon 5D MkIII camera kit and slider - all the way up - and back down again. Not once - but several times.
What's amazing is that Forbes uses his wide angle and slider to capture that sense of vertigo.
