As much as we like a good clean Model M specimen, those curly-corded clicky behemoths are somewhat lacking for certain flavors of gaming. There aren’t any blank keys to override, and there sure isn’t a full-color trackpad that you can write apps for. [Gus] has such a keyboard: the Razer Deathstalker Ultimate which features the SwitchBlade UI. He made himself this sweet audio visualizer for it that extends Winamp visualizations to the Switchblade UI.
[Gus]’s hack is built on the Tiny3D visualization framework. It does what you might expect—reads the visualization values, sets them up for display on the trackpad, and renders them to said trackpad. [Gus] uses some of the 10 programmable keys to change colors on the fly, and the result is pretty awesome. As [Gus] points out, this is just the beginning of what the plugin can do. You’ll need the Razer SDK to get started, and you can get the other ingredients from [Gus]’s repo. Once you’re done with this, you could try auto-dimming your keyboard backlight.
Of course there are demo videos after the jump. Come on.
Warning: coarse language, but has color switching
