I did in fact build the concole myself. It was actually pretty straight forward. It probably wouldn't work in a real club but it works just nice in my living room. :-) I'm pretty shure I have the plans somewhere. If you a copy of them let me know.
About the sign. It doesn't say "The Gay Park". But I guess you knew that already. :-) It's an old enamel sign for a company that produces wooden floors. Now if you could have seen the name of the company as well, I'm sure it would have made for even more laughs. The company is called "Junkers". :-)
