Next simulator update?

[Mathspy]

That's simple

First, use GRF Tool here http://ratemyserver.net/index.php?page=download_tool to extract the 'data.grf'
Then use SPR Conview (In same link as above) to view the sprites which you will find in /data/sprite folder

Inside the folder, you will see lots of folders with really awkward characters like "¸ó½ºÅÍ", don't feel weird, that's how this works
Use the Riot Bible to browse through the folders here:

It's little outdated, so anything you can't find it's sprite, just PM me ^^
