Moderlo MyBB Theme
Moderlo is a theme based on the styling of IP Board skins, as it is a popular style and layout i thought it would be a good idea to implement this into the design. This particular version is blue but there are plans for various colors if they are requested or this becomes popular.

Sleek MyBB Theme
Sleek is a theme which was originally going to be used on this site as the default theme, but i thought it would be better to allow others who like the look to purchase it. It is a fixed width theme based on the 1140px grid system and contains a collapsible sidebar where you can add extra stuff such as a twitter feed (which there is a tutorial for).
