Hm - this experiment should definitely be possible. First off, you may want to run through the lightgun experiment within the samples folder (group 6). You may also want to read up on the information found here:

If the right image is selected, you could then overlap the images or clear the screen and present either the check or the 'X' . If you would like, I can provide further assistance on getting this project started for you. Please let me know if you have any additional questions or if I can help in any way.

For help on displaying the images in this manner (a 3x3 grid), see the following link:
