modular Items

I stumbled upon This page and thought, that could be used to make all sorts of items. So i went to work with my programmer art and made this sheet. The coolest part about this system is you could have degrading tools as well as partial other items. Like the fish, you could have partial ate fish parts, there is a broken sword that could be drawn to reflect durability. once mapped you could draw the partial potions. 
Something im working on art wise but i haven't begun to start programming but i thought this would be a cool idea for someone that might want to have a more involved inventory  / item system in there games. I made the assets to have a base color that i could maybe change inside the game or like with the potions where it has a "fill level" with the color over lays.
