GLANCE

Track price changes and important sales with just a glance

Made by Hayley, Jeremy Jiang, Rajlakshmee Rajlakshmee, jknilans and kaylageer

Want to get that suddenly cheap flight while it's available or know when Nordstrom's is offering a 1-hr flash sale? How about if an item you posted on eBay is sold and needs to be mailed, or when your grocery store has your favorite foods on special? No need to log into your e-mail multiple times an hour or wade through all of the offers you've received when you can know the important information at just a GLANCE. GLANCE is an ambient device that acts as both a desk light as well as a glance-able notification device. Based on your needs, you can tell your GLANCE to notify you on a multitude of different price changes: *Amazon WishList Price Drops *Flight Tracker Price Changes *Price Drops at Best Buy *Ebay max price hit or winning bid notifications *And more!... ... For example, if you are tracking when rugs go on sale at any of your favorite furniture stores, you can set your GLANCE up to let you know if one does go on sale. No need to wade through your junk mail daily just to make sure you don't miss that sale you were looking for.

Recipes created on IFTTT send information between applications and Gmail and Spark.

Spark code writes a function to the cloud.

When Spark sees an unread email, it flashes the appropriate light, then stays on .

A second Spark function turns the lights off if the email is no longer marked "unread."
