Now that’s a weird title 
What I want to do is have a background app running in the webplayer that just sits in a corner of your screen without melting down the computer. In this phase everything runs slow at something like 1 frame update per second. there is some network activity and that’s it.
Only when something happens or when you activate the web window, the application “wakes up” and runs normally.
Is this possible in some way?
