Home Town Mystery

I visited my home town of Victoria, BC this weekend. I was inspired to take a few pictures of this amazing bonsai that my mom has in her living room. The most impressive thing about it, is how large the bonsai is. You can see how thick the wire is that was used to shape the bonsai into the desired position.  I am not certain what the variety of bonsai is, but since it has always been an indoor plant I am assuming it is not a Juniper bonsai like mine. Please let me know if you know what it is.
