Here is something I've been working on and it's something for your members to be able to choose a theme for thier profile. They can choose one when signing up or from thier profile page. Once the tip is ready to share all the code will be there so you can add or edit the css design for your own ones. This is still being developed but thought I would share how it's going so far. Next updates for this are for an image carousel under the choose theme options and then more options for layout type.
Anyways here is a video showing how it works
