NODEBOX DISPLAY MULTIPLE GEOMETERIES HOW TO
In place of a sequence of instructions which focus on how to do things, functional programming languages use chains of transformations that focus on the desired result at each point. A visual style demands a simpler, more fluid kind of logic.Įnter an old idea in computer science which has seen a recent resurgence: functional programming. This forces connections into arbitrary knots and loops, creating more tangles and going against the overall flow. The problem these examples have is that, although visual, they slavishly adhere to an imperative style of coding where instructions are listed in order and even the words within each instruction must follow a specific syntax. Reaching elbow deep into a rat’s nest of wires is not anything like shaping clay.īut it doesn’t have to be this bad. Stringing wires or snapping bricks gets really messy really fast. I think it’s easy to see at a glance the problem with this approach: it doesn’t scale. The others let you drag boxes around and string wires between them. Scratch) let you snap together commands like Lego bricks. The image above includes some typical examples. Instead of typing instructions, you drag objects around and connect them together to express ideas.Ĭlockwise from upper left: Origami (Quartz Composer), Coral, Scratch, Form In theory, any written language can instead be represented as a collection of elements arranged and connected in space this is the idea behind visual programming languages. Traditional programming languages are frustrating for visual thinkers they rely on a phonological style which uses hands only to type and eyes only to read. “With my hands” refers to a kinesthetic or visuospatial style of thinking which leverages our ability to perceive and manipulate spatial relationships.

There is no need to write a series of instructions and then “run” them to see what happens instead every change you make instantly affects the outcome. A familiar example is the spreadsheet: change a single cell and the rest of the sheet automatically updates.
There are two key concepts here: “continuously shape” and “with my hands.”Ĭode that is continuously shaped is called reactive programming. “I want to grab a clump of clay and just continuously shape it with my hands until I am satisfied.” I said I wanted a process less like solving a Rubik’s cube and more like throwing a pot. In my previous post I argued that the hunt is on for a better way to code, a way more suited for a designer’s need to test new interactions.
