How to use:

Copy and paste the minecart skin of choice to the desktop and rename it to 'cart', then drop it in the 'item' folder in 'Glimmar's Steampunk' texture pack.

The icons are colour coordinated with the minecart of your choice, but you don't need to use them to get the cart to work. However, if you want everything to match perfectly, you need to paste these co-ordinated icons over the top of the existing cart icons on the 'items.png' sheet in the 'gui' folder. Use a graphics programme that can handle transparency, like Photoshop, Gimp or Paint.net.

Many more minecart variations available in my thread OP on the Minecraft Forums, Texture Pack Section, Glimmar's STeampunk.
