Free Design-Joomla Extensions

Recently I've found a great site with the extensions (menus,components and modules).They are all completely free and can be used in every Joomla template. Currently the site contains 8 extensions:

• DJ-Art Gallery
• DJ-Catalog2
• DJ-Classifieds
• DJ-Flyer
• DJ-ImageSlider
• DJ-Menu
• DJ-MultiTreeMenu  

Site with extensions is available under this link - http://dj-extensions.com/
My personal favorite is DJ-Catalog2 component, which allows to segregate all products in a thematic categories, assigning photos or pics and other attachments to them.
