I can't easily find a photo of my bunny set-up, but I keep mine in a pen, not a cage. I have three Angoras (French/German mutts), all neutered boys, who live together. Aspen, Cedar, and Oakie. Their current pen is 8' x 8', out in my garage -- I have a three-car garage with only one car in it, so they're on the far side from where the car lives. Since the floor of the garage is concrete, I have a layer of old carpet down and then rubber mats on top of it (thick, heavy-duty ones, each is 4' x 10'), so they have traction and a surface with some give. Cedar has only three legs, so he's the one who needs the traction.
I use a fence/pen like this:

When I've had the bunnies indoors, I've used clear plastic panels on the bottom half, to keep the hay mess contained -- they get through a lot of hay, and it spreads everywhere. Because they're big rabbits, I use plastic under-the-bed boxes as litter boxes and wood stove pellets (made from only safe woods) for litter.
They don't really "play" with much, but that might be because they have each other for company? I'm not sure. They're VERY curious guys, but chewing is their only form of play. Their favorite things are their Coolaroo elevated dog bed -- now that they've realized it's for lounging, not peeing on -- and an igloo-shaped top of a big litter box that my cats didn't like. And any large cardboard box that I cut a hole in for them. They basically just like to be comfy and to have little hidey-holes. Oh, Oakie used to love an old cat tree that we had. He could get all the way to the top (he's always been something of a Tree Rabbit), but eventually I worried about him jumping down from that height, though he never did, and they just tore up the carpet and made a mess, anyway. But our current cat tree (for our actual cats) has more of a fleecy covering, and a smaller one of those could be a lot of fun for a smaller rabbit.
Their main passion in life is eating. It's really a joy to bring them a big bunch of kale or whatever and see how excited they get. Oakie turns his nose up at anything sweet, but the other two love getting little bits of banana or apple as a treat. They come inside for haircuts and the occasional hop around, just for something interesting to do. I usually have the big garage door on their side open for them when the weather is decent, for circulation and something interesting to look at. They're at the point where I can open their pen when we're outside, and they'll go for a hop-about. There was a very long probation period and close scrutiny to make sure they weren't going to do/eat anything dangerous, and of course we never leave them out if we're not there to keep an eye on them! A pen like the one above is nice if you want to take your bunny out for some time on the grass without the danger of a run-away bunny.
