TraceLab Turns Figure-Skating Moves Into a Language

Editorial interest 86/100 Selection signal · not a rating of the site

An interactive lab for composing figure-skating programs as siteswap notation and viewing the resulting blade trace.

Landing page captured for the 2026-09-02 issue.

Field notes

The tool models each skating beat as a state plus a transition, allowing a routine to be represented as an ordered sequence rather than a list of named elements. Its visible vocabulary includes states such as LFI and transitions such as 0SS, 0CT, and 0CS, while the trace can be mirrored, resized, and color-coded by foot. The page identifies synchronous two-foot notation as a future extension rather than a currently supported mode.
