Windows: Comical is essentially an RSS feed reader designed expressly for the reading of online comics. If you love a good dose of Amazing Super Powers or XKCD, you'll want to check out Comical.

Sure you could subscribe to your favourite web comics — Amazing Super Powers is featured in the screenshot above — in Google Reader or any other feed reader, but they wouldn't download and organise your comics for you. Comical not only retrieves the comics for you automatically, but it catalogues them on your hard drive for future viewing and enjoyment — so you're never stuck trying to tell your friend about that one comic you read last year that would be perfect for his presentation.
Comical comes with 41 popular web comics already listed in its database, you can add in any additional comics by creating a new entry and pasting in the RSS feed link from the comic's site. Comical is freeware, Windows only. Have a favourite tool for comics or comic books? Let's hear about it in the comments.
