Magic real time error/warning rendering using javascript snippet on a Table row??

In our next release,  Skuid will be including a new “ElectroZap” component.   Just like rendering conditions,  you dictate the data conditions that activate,  and there are optional properties for how big a jolt it delivers. 

(Oh - its not still April 1st is it? )

Seriously.  In javascript you should be able to evaluate some data condition in real time - and if the condition is true turn on a style.  Maybe the whole page background could turn red,  or a div could be changed from hidden to exposed.  Etc.
