There's also this website for anyone who would rather convert them for free online: http://iconverticons.com/
I use it all the time and you can find some pretty nice icons made by other users too if you click the tab at the top that says Get Icons. That's where I got a Haruhi folder for my anime. ^_^
Also, Merry Christmas to all!
Found Nodame Cantabile at Folderbooru (convert here or here)
All of my bots are open for your viewing. I use sqlite3 databases to keep track of post/comment ids, and whenever I'm about to take action, I check if that number is already in the database.
When I was very new to Python, I wrote a script for downloading the Recent Conversions on iConvertIcons.com. It uses a .txt to keep track of already-downloaded id numbers, so you can inspect that if you want. Overall I wouldn't recommend it.
If you have any more specific questions about it, I'm happy to help.
Here is the download link - there are MANY more compared to how many i've seen. Thanks to /u/shaydas and /u/UsifRenegade and all who contributed to this collection.
If you have requests go to /r/animeicons or you can make your own here - just google "anime name folder icon" and you should find something for any anime, then convert it there.
http://foldericons.booru.org/index.php
Look here before requesting, if nothing is to your liking, then request.
After saving the image that you want on Folderbooru, convert them to .ico here:

Have fun!
Didn't find any either, so I made you a few. I am yet to watch the show, so I hope the characters are right. I am also still pretty new to this foder icon stuff, so please tell me if anything doesn't fit right. These are png files, convert them here. Hope you like them
Edit: I tried to fit the logo onto the front lap. I think it looks a little better, but I'm not 100% sure with it. Maybe someone with a little more experience can fix that
Final edit! (I hope). So I worked a bit more on trying to make the logo fit onto the front lap. I think it looks ok now. I hope you like it, feedback/criticism welcome!
I've found ones for Index series, HSDxD, Log Horizon(yours), Infinite Stratos, SAO, and Mahouka Rettousei. Haven't found anything for Seirei Tsukai no Blade Dance, but it has an anime coming this summer.
I searched through this site. After downloading the png files I used this site to convert them to ico file format.
Usage: http://i.imgur.com/BXqgktj.jpg
If you place it in the folder you use it for you can give it a relative path*. To do this enter the folder and then add "/desktop.ini" in the address bar. This file will only exist after you have assigned a new icon to the folder.
In the file change the line
>IconResource=[folderpath]\Sora no Woto icon1.ico,0
to
>IconResource=Sora no Woto icon1.ico,0
*This means that it will always find the icon even if you move the folder.
Here are some alternative icons:

I didn't make any of the icons nor the tutorial.
Well you have two options there, either go to the individual download pages and save the preview image (IE right click and save rather than clicking the download button), or use http://iconverticons.com/online/ to convert them yourself.
I got lazy with mine also so I found some on Folderbooru.
Simply select which you like. Download it and convert it at iConvert Icons.
I made some icons for the episodes and I used the waterbending sign in one of them. If you want to use them as icons for folders like I did, use this site
There is also the background image to this subreddit.
