**What do you like the most about redstone?:** The idea that something with computability can be made with block positions and its states in a videogame is kind of *esoteric*. And I like it.

**What’s a thing you have made which demonstrates redstone knowledge?:** 4bit ALU with carry/borrow in and out.

**What does the thing do?:**

arithmetic a+b, a-b, b-a,

bitwise a∨b, ¬(a∨b), ¬a, ¬b, a∧b, ¬(a∧b), a->b, ¬(a->b), a<-b, ¬(a<-b), a⊕b, ¬(a⊕b).

**Image(s) and/or video(s) of the device:**

**What do you plan on making for your build trial?:** 4bit ALU with carry/borrow in and out

and arithmetic functions a+b, a-b

and bitwise logic functions a∨b, ¬(a∨b), ¬a, ¬b, a∧b, ¬(a∧b), a⊕b, ¬(a⊕b).

**Do you agree with the rules?:** yes
