A plugin to change window shape?

I like AVS a lot, and I have it running in windowed mode all the time whenever I'm listing to music files.

Yet I get tired of the square or retangular screen, and wish I could somehow change the shape to being more rounded, or circular.

Is there any such plugin that exists.....or something that allows you change the shape of the visualization windowed screen?

Thanks.

only thing i can think of is a really fat skin that partially covers the corners?

i'd ask in the skins forum
