Craftomatic

Craftomatic crafts items automatically from a template item placed in its left slot. The template tells the block what to make, and the grid updates to show the ingredients the recipe needs. Two types of crafter are being tested: a passive one that takes a hopper beneath it to collect items, and an active one that acts like a dropper. The author notes that it is unclear whether both types will be kept.

Where an item can be crafted several ways, arrows above and below the template let a player pick the recipe and choose which inputs to supply. Scrolling over the template switches between recipes, and multiple items can be used in cases such as dyes and arrows. Dropping an item into the left slot shows ghost items for what the recipe expects. The block keeps crafting until the remaining items are gone, and some recipes leave items behind, such as empty honey bottles from honey blocks, which flow out the bottom.
