Spherepop Prototype

( How ( + ( - ( 1 ) ( 2 ) ) ( - ( 1 ) ( 2 ) ) play ) spherepop: ( (Find the ( innermost bubble ) ) and then pop as many ( + b u b b l e s ) ) as you can ( . ) ) )

Spherepop is a visual programming language where nested expressions are represented as nested circles. Clicking on a circle evaluates the inner expression and updates the display.

Basic Principle

( ( ( a + b ) + c ) + d )

For the expression ((a + b) + c) + d, we will have a circle around a + b, a larger circle around (a + b) + c, and a larger circle around ((a + b) + c) + d.

Clicking on a circle will pop it and evaluate the expression within.
Scope Intro

Click on spheres to evaluate the inner expressions and watch them pop!

Basic Example

(((1 + 2) + 3) + 4)

Complex Example

(((1 + 2) + (3 + 4)) + (5 + 6))

Deeper Example

(((1 + 2) + (3 + (4 + 5))) + (6 + (7 + 8)))

How It Works

1. Nested expressions become nested spheres - Each level of parentheses creates a new sphere layer

2. Click to evaluate - When you click a sphere, it evaluates its contents and pops with a satisfying animation

3. Work from the inside out - Start with the innermost spheres and watch the evaluation propagate outward

4. Visual feedback - Popped spheres turn green and display their computed value
