This is how it's coming out so far:
Pictures are sent to the server, processed and sent back to the phone (emulator). I still haven't been able to test it on a real web server, but I've killed a couple of issues and it seems to be working fine! I've already used the "Share!" functionality, and successfully sent a couple of cool pictures to Facebook . However, there is still much work to be done.
Trying that with a real server might unveil connectivity issues (I'm not sure whether I'm using the best way to send/receive files), and I'll still need to work on the coolest part: Choosing the "transformations". Our plan is to create several apps with distinct functionalities or effects, and although grabbing edges already returns us some nice and interesting pictures, SimpleCV is capable of much more.
Let's see where it goes from here!
