问题
is it possible to tell a mobile browser, that as long as a certain HTML page is displayed, the device should not turn off its screen?
I want to build something like Project Blinkenlights, but every participant brings his/her own pixel. To set each display to a certain color at a given point in time is managable, just let each one open a website that shows a blank page and changes the background to color the screen. I'd use JavaScript to link the devices and have them log into a control server. But having the pixels wink out because the devices go to sleep would somehow break the concept.
A dedicated app would be overkill, and not every passing onlooker would install an app anyway (at least I wouldn't).
Thanks in advance!

I'm pretty sure you can't do that without bundle your webview inside an app. And whatever is the OS. It's all about protecting the user (and his device battery)
