I like this lamp, the "Pour Lighting," made by stuffing an Ikea fibre-optic Vedum lamp into an Ikea watering-can:
Here's what I did:
(1) sawed off the tip of the watering can with a hacksaw.
(2) cut off two of the legs of the base tripod (couldn't cut them all off because the wire runs through one of them and I didn't want to risk damaging the rubber shielding).
(3) Pushed the fiber optic spray portion of the lamp through the spout, hiding the tripod inside the can.
