I was really curious to try to write an app for WP7, but I didn’t have a whole lot of ideas. It’s hard to come up with something original when so many apps are already out there. And I don’t have capacity for a large complex app (if I had time for a very large app, I would write a decent GPS navigation software because it seems that Tomtom and Garmin aren’t in a rush to create a WP7 version of their systems).
Nevertheless, since I have some experience with math educational software, I decided to leverage my http://livegeometry.codeplex.com open-source project to try and create an app with at least some educational value. Writing a full-blown live geometry app on the phone didn’t seem plausible to me since the screen real estate is very limited and I couldn’t figure out how to make the interaction usable. However it dawned on me that a little “fun facts” or “geometry gems” gallery would look quite nice on the phone.
So here it is: http://social.zune.net/redirect?type=phoneApp&id=5e8194b7-d0ea-df11-9264-00237de2db9e
(or just search for “Live Geometry” on Marketplace).
It’s a collection of 35 interactive geometry drawings each of which illustrates a certain fact or a theorem of elementary geometry. As always you can drag the points around to experiment with the construction. Here are the screenshots that you will also see on the marketplace:
Amazing! Also your live geometry open-source project!
Kirill, I realise you're probably not look at this much anymore.
I've kept an eye on your live-geometry project for a long while. You helped me with a geometry problem in 2010 I think it was.
Do you have an source code or small WP7 project to look at?
Very curious as I am looking at porting my drawing tool to WP8 and W8 too.
unfortunately I can't share the source code for WP7 app at this point. Sorry and good luck!
