Alas, I haven't got a picture.
Still, you know the folding luggage racks they have the a hotel room? Two metal-pipe frames, with nylon webbing straps, unfolds into a sort of a thing you can set your suitcase on?
Set it on end. You will need some magazines to prop it up a little. It's very wobbly otherwise. Now you have 4 legs, the "front", pointed at your model, and the nylon web mesh opposite, on the "back".
Hang a towel over the legs, place a strobe behind it pointing up.
Instant.. softboxish scrimmish thing. It softens the light, anyways. Inefficient as heck, and it leaks lights all over (throw a blanket over it to contain things a bit if you like).
