  We describe a newly-developed, free, browser-based application, for the
interactive exploration of the dynamic geometry of Poncelet families of
triangles. The main focus is on responsive display of the beauteous loci of
centers of such families, refreshing them smoothly upon any changes in
simulation parameters. The app informs the user when curves swept are conics
and reports if certain metric quantities are conserved. Live simulations can be
easily shared via a URL. A list of more than 400 pre-made experiments is
included which can be regarded as conjectures and/or exercises. Millions of
experiment combinations are possible.
