Not altogether that amazing, but maybe this'll come in handy for someone. (I know of two uses for this - one in a script I made, and one in a script I plan to make)

Note that Toribash's semitransparency doesn't really work all that well, because depending on the drawing order, semitransparent objects may still block view of stuff.

You can change the alpha value by changing the a variable in the script. (0 = invisible; 1 = opaque)
