Catalook - We have been Doing custom Catalook skinning for a long time. We normally combine it with DNN skinning projects and we ensure that the catalook looks great in whatever design we have done for DNN. Please see one example here.

Active Module - Same here and we have indeed done number of skinning projects for this great Module.

Ventrian Modules - These are Modules by Ventrian Systems like their very popular News Article Module or Property Agent. As well as the side Link module which is especially useful to show the child tabs in a stylish way.

Portfolio Module - is another great module that we use as part of our store solution. See it here in action in our store page. Or perhaps extensively used in our property sites.

Real Estate Module - Web Amazing Real Estate Module is another great module that comes with not so good UI and we are able to configure and skin it for you. See one example here for Property search and here for Property letting.
