Create a fully working clock using Cloudinary

Ever wanted to make your very own fully operational clock? This recipe would show how to create a dynamic clock in one URL. You could then insert the URL anywhere you want and have a fully working clock image that dynamically changes with the time. This clock leverages cloudinary's Overlay and powerful user variables which allows it to show an accurate hour based on the actual time.

Waveform creation

You can create a waveform from every uploaded audio or video (which includes an audio channel) file. Simply use the waveform flag (fl_waveform in URLs) and set the file’s extension to any image format you like.
