Light Fixture ~Modified Halogen for Art Exhibition

I don't know if this will actually work, but I know that I haven't seen anything like it on the internet yet. It's a light made to house halogen bulbs for art exhibitions, a track or hanging light. The shroud is shaped into a trapezoid which I hope will project a rectangle onto the wall surface, with more light compensating toward the top of the fixture. The angles are much different than a cylindrical can too, but I just want to try something more bar or rectangular in shape.
