i ordered this frog at dealextreme. com.Its called a "Digitally Recordable Motion Activated Visitor Welcoming Door Chime Frog". Originally it is a toy that says "Hello" when someone passes by. You can use your own sample, simply by pressing a button to record it to the frog.
Nice toy for circuit bending i thought. Here's what i made today. I added loop, pitch control, input and output jack and a button to start the sample manually. Okay it has still a few bugs, but it works.
Hope you enjoy the video:
