Funnel-web is a non-engineering membrane modelling tool for use in artistic design. It allows a separate force for each membrane point and pinning of selected membrane points. It is a work in progress; planned future extensions include an option for automatic seaming of points in common, allowing multiple Funnel-web membrane components to properly run at the same time, and accepting non-grid point input.
Funnel-web also includes a simple force-directed graph component for displaying relationships and so on.
