Here is a theme i have done quite a long ago from now may be an year and half,but still it is one of the most downloaded theme in mybb.
The main speciality of the theme is its ability to change colors with a jscript switch,which changes the entire color of the theme and hence the name,"Chameleon".
It has :
Quote:1.Color switch with 3 primary colors : Blue,Red,Green
2.Drop Down main menu
3.Jquery based tool tip on every icon.
4.Floating panel on header.
5.Jquery based category description.
6.Post bit drop down menu
7.Css3 based rounded borders.
8.Css based post buttons with contra bordered.
9.Color switch is noted in : All Pages category-forums-profiles,Post bits,Buttons,Tool tips,
,footer copyright and its for you to explore.
The best thing is it also changes the BACKGROUND,and this is first of its kind in this regard.
