A neat interactive visualization http://www.lkozma.net/cuckoo_hashing_visualization/
Edit: as child comment points out, this is a visualization of normal cuckoo hashing, not cuckoo++ that this paper describes.

From the paper: "we describe algorithmical changes to cuckoo hash tables allowing a more efficient implementation. More precisely, our hash table adds a bloom filter in each bucket that allows to prune unnecessary lookups to the secondary bucket."
