Tune Brainwaves While Browsing the Web!

This would only work on websites that have a solid color background (not a tiled image):

The extension takes the background color of the current page and flashes it between two shades, one lighter and one darker than the original color.  The contrast between these two shades, and the rate of flashing would be configurable from a popup control panel.

The adjustable contrast prevents the flickering from becoming too distracting from actually reading the websites.

I've previously made a strobe light application: http://omnidelic.com/strobe (tested with Chrome and Firefox)

Future versions of it could introduce sound synchronized to the flashing, and also the ability to work on image-based backgrounds by adjusting the colors in the images.

Download

SiteStrobe is designed as a UserScript, which adds extra functionality to each webpage loaded in the browser.

sitestrobe.user.js

Install

Firefox NOT WORKING YET STANDBY First install the GreaseMonkey extension and drag or open the userscript into Firefox.   It will now appear in the GreaseMonkey menu.

Chrome  Simply drag or open the downloaded userscript in Chrome.  It will ask for confirmation.  You can manage it in the Extensions menu.

Usage

SiteStrobe is currently controlled by a few key shortcuts.  In the future, a popup panel (like Omnidelic Strobe) may be added.

Caveats

• DO NOT USE IF YOU OR SOMEBODY NEAR YOUR SCREEN SUFFERS FROM EPILEPSY AND DOES NOT WANT TO RISK A SEIZURE!
• SiteStrobe may not work on all websites, since some site designs cover a significant part of the website with non-background colorable content.  Future versions will fix this by letting you "erase" certain backgrounds that hide the strobe.
• Make sure to disable SiteStrobe when you leave a tab or window, because if you leave several pages strobing, you'll notice it consuming CPU even when you're not viewing it.  We plan to fix this in future versions by detecting when a tab or window has become invisible.

Lucas Whitefield Hixson: Can you associate it with iso-tones? Have set playlists with iso-tones matched with background visuals

Peter S Sysko: you really need ADHD to understand how cool this would be. I think it could be really fun to play around with viewing websites with our own CSS rules... try to incorporate that.. not just flashing.. but having totall css revision control over other peoples websites..

yeah, animated CSS rules. i like that generalization. it could also work on font sizes: making font sizes pulsate would be entrancing

yes i think it would have multiple uses. it might help some people focus better, and if nothing else it would make browsing more "interesting"
