MemorizeIt is an app I'm currently working on. I'm using C# and OpenGL ES 2.0. Currently it has three categories:
Memory: a simple game where two images have to match (needs at least ten images)First start will take some time for thumbnail image creation. The images are taken from the storage card in the directory "DCIM\100MEDIA". Additional images (.jpg) can be put in a directory named "TestImages" located in the root of the storage card. Saving of image effects not yet implemented.
Head Tracking: an experimental image browser
Image Effects: apply shader effects on your images
update Nov 8 2010
check if directory TestImages on the root of the storage card exists
update Nov 14 2010
Image Effects: browse and select images (left-right scrolling)
Thanks for any comments, test results or ideas for improvement!
