Okay, so I'm going to, let me take a look at Planetoid, which is an app built by Derek Bacillou, that allows you to view the positions of the planets around the sun. And Derek and I have been talking about a lot of improvements to the app, but I just want to give you guys a demo of what the app can do right now. So basically we have the sun and some of the basic planets of the solar system going around the sun and we can see by date where the positions of the planets are going to be. If I take my hand, I can move the angle to view the planets from the side and there's a Jupiter just popping in. So we can look at the planet totally from the side angle, from a point in space to see what the positions of the Mars. And we can also zoom in. You've got to close your look. There goes the Earth passing by. Mercury. Do you want to put a loop? Well, we can see right now we're in the year 2016. Time can be stopped. So you can shift around then. And even zoom in. Get a closer look. So it helps understand why we can see certain planets at night during certain times of the year. We can go really fast forward. Or we can slow it down. Go backwards. Some of the improvements we're going to make to the app include the ability to click a planet and then track based on the planet itself instead of always being centered on the sun. And also to be able to control speed or jump to a certain date. But this is just a basic video of the functionality. So you get an idea of what the app can do. That's available on Android Market. I will post the link in the video. I think we can use it download. Thanks for watching.
