Tree of 40 Fruit

Surprisingly the "artist" uses the same fake picture on their site as well. There are a few minor pictures of multi fruit grafted trees which you could find if you went to any garden center as they are quite common.
This seems like something destined to impress people who don't know any better. I'd love to see the actual 40 grafts tree in action but it seems to be agricultural vaporware.

Look at the transition at 29 seconds in that talk [1]. The clouds are in the same place.

I don't hold anything against the artist though, the article just picked a terrible image to use.
There is also a group in SF that grafts edible grafts on decorative urban trees, such as on Japanese cherries: http://www.npr.org/blogs/thesalt/2012/04/07/150142001/guerri...
40 varieties of fruit sounds a lot nicer than 40 pounds of black walnuts (which have a thick, tough, stinking skin if you even think you want to harvest the nuts).
