Custom crosshairs for TF2.
IMO the default crosshairs are huge but the designs are ok, so these are simply the default crosshair designs (credit to valve) but smaller and in a variety of colours.
Installation: Copy/Paste the colour you like into your:
\Steam\SteamApps\username\team fortress 2\tf\materials\sprites
Directory (if you do not have this directory then create it) and rename to Crosshairs.vtf
