Copy of Rio trophy that you can buy on eBay.

It appears instead of flowers, Olympians on the medal stand got a 3D printed sculpture.  This was said to be less wasteful than flowers and I suppose more of a long term keepsake.  You can read more about it here and even buy your own version on eBay like the picture above.  I suppose it beats the old Isthmian games in ancient Corinth, there if you won you got a crown made out of celery!
