After hearing and seeing what iskall was trying to do I thought that that would be a great item to add to my mini game that I am currently working on.

There are two versions available in the world download. A version that works the way iskall wanted his to work with all items costing the same amount, and a version that works the way I needed it to with increasing price. They are both built to not allow spamming of buttons to get multiple items and light up when there is enough rotten flesh to pay for the item.

If you wish for the currency to be something other than rotten flesh just change the item sorter to accept whatever you would like.
