Nothing "modern", but may qualify for the "funky" part or maybe neither.
This is a 6' x 30" x2' cage. I've cycled several animals through it. Every one of them has used the perches and open floor area.
These are 4 footers of various heights. The bottom cage is 30" deep the others are 2' deep.
I suppose the only "funk factor" would be the lighting outside of the cages. The lava lamps and other lights have a retro appeal. I like to relax in this room and I will often put on a rainforest soundtrack and watch the animals when I have time.
I enjoy the setups and creating the environments. Occasionally, I will see what others have done and change some of the interiors of the cages here. The larger snakes get a turn at the big cage depending on their activity levels. Currently the 10 year old boa is using it.
