A new meaning for the word Slack.

Lately on youtube, there's been an ad for a computer program called Slack, where a group of animals use Slack to make flying umbrellas. Even before the ad included bloopers, I thought the ad was cute, and showed what Slack could do. I do however, find it kinda strange that such a useful program is named after a word that refers to someone needing to do more, or is lazy (in this case: Slack). Still, Slack and the animal ad for it do look useful and fun.
