DIY line tester and lightbox

I must say that I am quite proud of this. A reasonable A3 lightbox purchased from Amazon, with a cheap webcam with LEDs also from Amazon, costing me roughly £55 in total. I created a small pocked out of cardboard and taped it to the front of the lightbox, this allows my metal ruler to slip into the pocket when line testing, the webcam can then be clamped to the top of the ruler.

This means the line tester can be removed whilst animating.

Very efficient.
