Is there a real-life computer mouse that looks like the ones in "Portal"?

[LOTA]

I want to find a computer mouse that looks like the model in Valve's 2007 game Portal, to which I can add an Aperture logo as part of recreating the Aperture Laboratories PC setup shown in the game.

The in-game mice have an off-white upper shell with sweeping grooves/gaps separating the main body from the left and right mouse buttons. Between the two main buttons is a slightly-recessed medium-grey section that appears to contain three dark-grey buttons for (presumably) scroll-up, middle-mouse-button, and scroll-down (though it's possible this is intended to be a grooved scroll-wheel and only appears flat because the model is so low-poly). The bottom is medium-grey with a slightly-off-center red light and optical sensor, plus three dark-grey circular-arc feet/skates. The in-game model is approximately 2 inches left-to-right by 3.5 inches front-to-back by 1 inch top-to-bottom, which may or may not be accurate to real life.



Does anyone know of a real mouse I can buy that looks like this (minus the logo, of course)?

If you interpret the edges as being a jagged approximation of a mouse with round edges, then I think there must be a matching mouse out there somewhere.
The area in-between the buttons may not be grey, but that is a part that could be painted.

Yes, I'm assuming the angularity is just an artifact of the low polygon count of the 3D model. I'm hoping the game developers based the model on a real mouse design, but I haven't been able to find one.
