Awesome idea!
You definitely should have mining equipment on display - examples of CPU miners, GPU, FPGA and a cheap ASIC, along with maybe some of the mining pools shown on screens?
The other thing I always thought would be so cool would be to have a set of monitors on the wall with live price tickers, showing the different currencies.
And of course be ready to handle the media inquiries!
You read in my mind

I'm dreaming of seeing that wall!
Mining equipment will definitely be considered. Good point for the medias though, didn't taught of that. This project could become the "face" of Bitcoin around here, and we need to be prepared.
Thanks for the links, they are a interesting model to consider. The first floor of the building has to be a sort of information center/bitcoin shop. It has direct access to the street with big windows and doors. The two other floors have a separate access from the first and that's where we could be more "creative" on their activities.
Hello!
I am very excited about developing the Building into our center. Thank you for the ideas. Keep them coming! We should try to meet-up soon again to sort through the suggested activities, choose those we should focus on at the launch of the Center, go through the design of the layout in some measure of details this time, and discuss some anticipated challenges we are certain to face in promoting the use of Bitcoin in Quebec & Canada.
Next Saturday for another meet-up?
