Tick Tock is a tool for helping a speaker know how much time they have left for their talk. Tick Tock can be used on a PC, smartphone or tablet.
If you're hosting an event and want to use Tick Tock you can fork this
repository and drop your logo into the HTML on the gh-pages branch. For an
example take a look at the the Github-branded example (code).
Replace the URL of the octocat and your logo will be displayed in the top-right
of the timer.
