Netflix engineers have built some interesting features for the service, which could be quite popular with users, but they may never (and probablywill never) see the light of day.

This of course means Netflix had another Hack Day. They hosted one in February, and came up with some pretty cool stuff. You can read about all of that here.

Last week, they did it again, and have now shared some highlights:

Netflix said on its tech blog:

The teams produced hacks covering a wide array of areas, including development productivity, internal insights tools, quirky and fun mashups, and of course a breadth of product-related feature ideas. All hackers then presented and the audience of Netflix employees rated each hack on a 5-star scale to determine our seven category winners and a “People’s Choice Award.”

Below are some examples of some of the hacks to give you a taste of what we saw this time around. We should note that, while we think these hacks are very cool and fun, they may never become part of the Netflix product, internal infrastructure, or otherwise be used beyond Hack Day. We are surfacing them here publicly to share the spirit of the Netflix Hack Day.

I’m still holding out hope for the DVD delivery drones.
