was it the condiment stand or the smaller ones? we dont even have an ikea here but i have a feeling ill be making my own pretty soon in my spare time
Honestly, you could use any of the containers in that link, they all connect to those little hanging hooks, so you could simply pick the size container you want. You could also use any of the dish drainers that attach to hooks and put pots on those. That's why I just linked to the whole page instead of just one item, there's lots of options there.
My main problem is that I have no construction or designing skills; I have no idea where even to start. And since Fred like to bulldoze his way through the tank, whatever goes in there has to be pretty sturdy and sturdy isn't the first thing that comes to mind when I think of my craftsmanship.
In that case, you could do what I did, and go through this forum, looking at the various designs, plus google paludariums and look at what other people have done, and pick and choose elements that you like. It takes time, but it's worth it. One idea that comes to mind is to create a custom background, that would liven things up quite a bit. You could also use the idea I mentioned above to get trailing plants hanging down into the tank. I also know that there is one GABF tank in this forum that someone set up to look just like their natural habitat that is very cool. If you do a search here on African Bullfrogs, it should pop up.
