So I've had my Microsoft Natural Ergonomic Keyboard 4000 for about 15 months now. It is fantastic and very comfortable to type on. I'm getting a bit bored with the colour scheme however and am thinking about how to modify it. So far I'm considering painting the grey trim and replacing the function lock LEDs with different coloured ones. Also probably applying braided cable sleeving to the cord. What I want to know is, do you guys have any ideas of what I could do? Done/seen any keyboard mods? Pictures would be appreciated. Thanks for reading.
