Connect with puzzle enthusiasts worldwide as you master balance mechanics together
The studio behind Leprechaun Wish actively engages with the builder community through forums and in-app feedback. Monthly updates frequently incorporate player-suggested materials, challenge modes, and interface improvements. The development roadmap is shared transparently, with community voting on priority features. This collaborative approach has shaped the app into a genuine platform for physics puzzle enthusiasts rather than just a standalone game.
Precision tools and physics systems trusted by our builder community
Design hanging mobiles with up to seven interconnected tiers. Each arm calculates torque distribution in real-time, showing left and right weight forces measured in gram-millimeters for perfect equilibrium.
Position knots with 0.1mm accuracy using interactive adjustment controls. On-screen rulers and alignment guides help you achieve professional balance points while the app calculates tilt angles within fractions of a degree.
Vector editor with drag-handle control points lets you create unique cut-out designs. Calculate exact drill points, centroid positions, and mass distributions before cutting your physical materials.
Choose from basswood, heavy card, wood felt, and plasticard with authentic density properties. The app automatically adjusts mass calculations based on shape area and selected material for realistic weight behavior.
Auto-generated inventory of ceiling screws, swivels, jump rings, and split rings needed for your specific design. Each item includes quantity counters and assembly instructions to bridge digital planning with physical building.
Track total mass, vertical drop distance, horizontal span, and completion percentage for each mobile. Pie charts visualize weight distribution across materials while detailed specifications prepare you for real-world construction.
Deep dive into the physics simulation powering every balance calculation
Leprechaun Wish implements a genuine physics simulation engine that calculates torque, center of gravity, and rotational equilibrium for hanging mobile structures. When you adjust a knot position by even a tenth of a millimeter, the app recalculates forces on both sides of the fulcrum and displays the resulting tilt angle using trigonometric functions accurate to the limitations of physical cord flexibility.
The geometric editor uses vector mathematics to determine centroid positions for irregular polygon shapes. As you scale a traced design, area and mass update dynamically based on the selected material density constant. Drill point coordinates are calculated relative to both the shape center and the bounding frame, ensuring your physical cut-out will hang exactly as visualized in the digital preview.
Project data persists across sessions with cloud sync support. You can export mobile specifications as formatted lists containing all measurements, material quantities, and hardware requirements. The interface follows blueprint aesthetics with dark navy backgrounds and golden accent colors, creating a technical workshop atmosphere that appeals to both casual puzzlers and serious engineering hobbyists in the community.
