Does anyone know if it's possible to mod the GUI images (inventory, attack buttons, etc.)?

I looked in the assets pack but couldn't find anything... any ideas? Thanks in advance.

I haven't been able to find them, either.

It might be possible to change the GUI graphics with the "GraphicsContext.draw" functions.

You could also take a look at the GrimTK GUI Framework. Maybe the programmer knows how to replace the GUI graphics.
