The Songs of Johnny Go

Home Depot is your friend. The bigger ridged tubes are dryer hoses coated with silver spray paint, while the smaller black ones ... I dunno, you'll find something. For the front panel designs, rather than trying to make them textured, just go with magic markers to draw that shit on there, although a rule and a compass are your friends to get the lines and the circles neat. From there, all you need is some brown boots that you can attach red straps to, and you're all set.
