We have published a post about Send Notifications Instantly with Growl Mootools few days ago. And then one of our readers, Oskar Krawczyk has pointed out that there is another Growl-like notifier called Roar which is more configurable.

Roar is a notification widget that streamlines incoming messages, such as updates or errors, without distracting the user from their browser experience or breaking their work-flow by displaying obtrusive alerts. Roar is inspired by Growl, and is realised with MooTools as well. You can check out the following 3 examples below.

• Never-ending Feed Showing feed items with link but without end.
• Random Alerts Random notifications for all 4 corners of the document.
• Update Ticker Timed updates on events.

Roar has been tested on all A-Grade Browsers and it is available under the MIT License.

Requirements: Mootools Framework
