I just completed my display for the Tumbler and dx-12 Batman. I built them into some custom cabinets I made for my batcave. I'm about to build a custom desk with the Batpod and Selina Kyle display as one of the sides.
I've had a a lot of fun building this. The only issue I had was the space constraints. I would have been nice to build a display large enough for all the vehicles and hot toys TDK figures.
