Outside of the flotation device, I see a couple concerns. If this is the end all for you, I would consider the following: 1)the buttons are far apart 2)why are the joys so far from the buttons? and 3)If you plan on making this the control panel you will have for a long time, why not leave space for a trackball if the funds ever become available? If you cleaned up the spacing a little, moved each player to the left and the right, you could leave space for a spinner, trackball, flight yoke, or any add on for later use. Shoot, you could make the middle a pedestal of sorts for usb plug ins like steering wheels and flight yokes. Just an idea for future planning.
