I can see this product improve in a few different areas. One can proceed to actually make a mold. That way one can create any kind of animal they feel is their spirit animal. I also believe that adding sound would be a good idea, incase the guest is concentrated on what they have to say and don't notice the waving bear. 

I learned a lot building this device. For example you need to be able to use a material that wont get in the way of the waving hand. Also, learned that glue might be a better option than electrical tape.
