Deffect (Dialog Effect) is an interactive Dialog play-thing controlled by your mouse. I simply experimented around with dialog controls. My original intention was to make a dialog "Pong," but there's really no way of moving around dialog features.

;Dialog Effect 1.0.1 
;Made by BlueThen on January 17, 2009. 
;To open, type /deffect or right click the channel/status and click "Deffect." 
;Controlled with mouse.
