RNS:: Butterfly - Effects:
These graphical effects are a pleasure for the eye and can sometimes be quite useful.
To see the effects, open the "Effects" screen in Butterfly.
Candle is a romantic effect, useful especially when you don't have a real candle. You can change the candle color and "burning" delay.
Colorfade will make a warning light out of your handheld. You can change the faded color and fading delay.
Discoteque is very effective especially in a dark room. Not really for a disco, though. You can change the fading delay.
Flashlight is a simple effect. The screen fills with the selected color. In general, you should use it with light colors.
Signals are similar to the Flashlight effect. You can change the signal color by tapping the screen:
Spotlight - and everybody thinks you have a real torch. You can change the bulb color.
Check the "Keep on" checkbox to prevent the device from turning off while showing an effect.
