The above image shows a 2D photo on the left of several roses in front of a porch that was submitted to a competition for entry into a photo context at a local art center. Immediately to the right of the 2D photo is a 3D tactile print of that photo with text above encouraging one to touch and press down on the 3D print which then generates an audio description of the 2D photo. Underneath the 3D print is an audio generating device similar to those used in "talking greeting cards". An image of the audio generating device is shown below and the audio produced can be heard by selecting the link at the end of the image description below.
The above image shows the audio generating device designed to play recorded audio when the pressing of the 3D print on the other side pushes down a switch on the device which completes a circuit and generates the recorded audio describing in more detail the 3D print made from the 2D photo.
