Unlock starter libraries, premium optimization features, and rehearsal analytics designed for performing professionals.
All features available in Northern Smile v1.2. Optimization quality depends on library metadata accuracy. Rehearsal mode requires active timer permission.
Northern Smile combines taxonomic effect-plot classification with computational set theory to solve the running-order problem professional magicians face when constructing shows.
Proprietary algorithm sweeps through trick permutations to minimize prop-reset conflicts, avoid back-to-back effect-plot repetition, and maximize audience energy distribution across the performance arc.
Visual representation of predicted audience engagement over time based on trick impact ratings, difficulty levels, and placement within opener-reset-climax structure. Export curve data for show analysis.
Real-time performance simulation with per-trick timing, cumulative duration tracking, and pace variance indicators showing ahead/behind status relative to target durations.
Automatically flags running orders requiring mid-show prop resets based on angle sensitivity tags, reset time metadata, and prop-family classification across the trick library.
Structured tagging architecture covering 11 prop families, 10 effect-plot types, three-tier impact/difficulty/confidence ratings, and angle sensitivity classification for comprehensive trick profiling.
Aggregate analytics showing total duration vs target, effect-plot distribution histograms, prop-family balance charts, and optimization status verification with green checkmark indicators.
Northern Smile implements a constraint-satisfaction solver that treats set construction as a multi-objective optimization problem. The engine evaluates thousands of running-order permutations against weighted criteria: prop-reset minimization, effect-plot diversity enforcement, energy curve smoothing, and angle-sensitivity compliance.
Each effect in the system maintains 12 discrete metadata fields spanning categorical tags, quantitative ratings, temporal parameters, and relational links. This structured approach enables the SpineEngine to perform set-theoretic operations on trick collections, filtering candidates based on compatibility matrices derived from prop-family intersection analysis.
The rehearsal subsystem runs a millisecond-precision event loop that compares actual elapsed time against target durations stored in trick metadata. Variance calculations update in real-time, providing ahead/behind indicators that account for cumulative drift across the entire set rather than isolated per-trick measurements.
Northern Smile was architected by performers who understand the cognitive load of show construction. Rather than offering generic list management, the application implements domain-specific intelligence derived from decades of professional magic theory regarding audience psychology, prop logistics, and theatrical pacing principles.
