Can't think of any videos Nige but I'm sure the membership could come up with one hundred and twenty three uses for them.
Here are a few for starters.
Packing up work so you can make holes right through and not into the mill table

Something to increase the base of a wixy

Poor mans gauge block to set spacing of webs to 10mm

With ones from ACR that will screw together you can form a right angle so multiple parts can be set against the "stop" that they form to save resetting for each part

If like me you use an electronic edge finder then a 10-20-40 block gives a metal edge to touch when working with plastics etc
