Did you say you wanted something cool... and for free? OK, fine! This countdown timer is the perfect thing to display when you send your online class out on a break (and you're concerned they'll just never come back on time). The time is an Adobe AIR application that will run on Macs and PCs and features custom away and return messages, along with multiple timer settings. You can download the timer, along with several other eLearning assets (again, all free) here.
