All episodes of Circles furry gay-themed comic released to February 2009.
In a very comfortable and easy-to-use .DJVU format, with good, free apps to open it.
Why it's better than other releases? It's only 258 MB instead of 1600 MB - less time downloading, it's much more comfortable to use - you read it fitted to your screen like a book, instead of opening and closing single .jpg images, which were about 6000 pixels high, I don't know why so big.
The quality of images is very good, the compression is low, and they're all 3000 pixels high - it is still a large amount.
