I love this gift! It is on my wall at my office and makes an awesome swishing sound just like the doors in TOS Star Trek. Love it. Everytime I walk into my office it is like I am on the set of the original series. So much fun. THnak you thoughtful gifter. I am sorry this post was late. To be very honest I ended up in the hospital and have be not well the last couple weeks. Nothing fatal just painful and distracting. So that is why this is so late getting posted.
