A lamp inspired by the book Harry Potter and the Deathly Hallows.
The shape is the symbol of the Deathly Hallows. The vertical line (cable with bulb) represents the Elder Wand; the circle, the Resurrection Stone; and the triangle, the Cloak of Invisibility.
PS: This is my second version. I used Bevel instead of Edge sharpness on the smoothed middle tube. I must say it looks muuuch better.
