Click on the magnifying glass icon (below the artwork) or select 'open the link in a new window' in your browser for accessing the interactive animation. This interactive document is a SVG live clock inspired (though different) by the Swiss Railway (SBB CFF FFS) iconic station clock by Hans Hilfiker. See <https://www.sbb.ch/>. The document also features vectorized portions of the free and open source font 'Fira Sans' (light weight used). See <https://carrois.com/typefaces/FiraSans/>. The hand colors are chosen according to the RGB canonical color scheme. It is a mnemonic: Red for seconds, Green for minutes and Blue for hours. A JavaScript dynamical simulation is running in order to animate the clock hands. Click on the hands to perturb them. Ctrl+click changes the direction of the perturbation. Shift+click increases the perturbation impulse amplitude. Ctrl and Shift can be combined. The (embedded) script for the dynamical simulation uses Math.js (version 3.16.4, embedded as well): <http://mathjs.org/> V1.0 (04.10.2017): Initial Design V1.1 (06.10.2017): Design Update (the initial version was identical to the SBB CFF FFS clock, leading to potential copyright issues) Copyright (C) 2017 by Fabien Fellay The script is licensed under the GNU General Public License version 3 (GPL-3.0). <https://opensource.org/licenses/GPL-3.0> <https://www.gnu.org/licenses/> The artwork is licensed under the Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0). <https://creativecommons.org/licenses/by-sa/4.0/> --- Curated by Martin Owens on October 6 2017 2:55 PM
