I had trouble listing the 2.5 version through the JED so I'm just combining the listing for the 1.5 version with the 2.5 version.
Both extensions are free to download on the website...enjoy!
ArtCats is a module that can automatically list Articles from within a designated Category or can list Categories from within a designated Section. Compatible only with Joomla 1.5 and later. Not for use with Joomla 1.0.xx. Based on Categories 1.5 module created by Rich Dorfman which was created with inspiration from Module - Content Categories version 1.0.1 by Boris Komraz.
2.5.0 version announcement:
New version 2.0.4 with "Exclude Current Article" ability now available!

Please post questions there in the comments section or email me!
Additional Information (Please feel free to visit the Demo/Documentation Pages as well):
When set to auto mode this module functions contextually, meaning that it will only return the expected links when on the appropriate type of page.
For example, let's say you had a Section named Section 1, with Categories named Category 1, Category 2, Category 3. Let's say you also have another Section named Section 2, with Categories named Category 4, Category 5, and Category 6. In auto mode the module would automatically show links to Category 1, Category 2, and Category 3 when you visit the Section 1 page and show links to Categories 4, 5, and 6 when visiting the Section 2 page.
For Categories the functionality is similar. Let's say you had a Category named Category 1 with Articles named Article 1, Article 2, and Article 3. Let's also say you had another Category named Category 2, with Articles named Article 4, Article 5, and Article 6. If you visited the Category 1 page the module would automatically show links to Article 1, Article 2, and Article 3. If you went to visit the Category 2 page the module would automatically show links to Articles 4, 5, and 6.
Pretty nifty huh? I figured this would be a nice way to have a semi-automatic menu system.
Your ideas are welcome!
