Transparent Overlay

Imagine a standard transparency (typical in overhead projectors) with a triangular (like a pizza) simple but accurate fixed angle grid printed on its' surface. I am interested in a program that can print such a shape as a software overlay that can be freely and VERY easily dragged and rotated through 180 or even 360 degrees and moved generally around the screen using the mouse preferably. If the triangular shape is dragged to the right so that the apex is located well off the screen then the shape will just expand in size from the left (bigger triangle) but still with the same angles. The overlay needs to be transparent except for the triangular grid so that it can visually display the program running underneath yet still allow the overlay to be moved rotated etc. Is such a thing possible ?
