On another note... ok check this out. My dad and i came up with this one. Have this window in your living room, a very large circular window, say 5' across and make it convex(out from the house). Sit and watch as people approach the window to admire the view as their faces are burned off by the sun like a bug under a magnet. This would really work! Sick yet interesting.
