yes, a homemade riddle -
just some old weldmesh netting, some garden wire, a bit of old rope, and a hour or two with a pair of snipe nosed pliers and side cutters. Oh, and a pair of 2nd hand but originally very expensive alloy racing bike rims...
shows what can be done with a bit of lateral thinking. And it cost nowt (well, the garden wire was new so i suppose about 20p worth of that)
