Organizing a closet with slanted ceiling

I was recently on Tip Junkie's blog and saw a comment from Joann asking about utilizing a closet with a slanted ceiling. I identify that it is not always easy to utilize the space.
This featured space was added when we were choosing paint colors for our gameroom/media room. While I'm cocking my head sideways at the sample colors on the wall my husband is knocking on a corner space saying he thinks he found some storage space behind the wall!
Then he gets a hammer and knocks a hole in the area. My eyes were like saucers!
But behold, there was definitely space there that could be used even though the roof slants in the area.
I wish I had photos of him with his hammer!

I group like things together. As you can see the shelves are graduated lengths to utilize all space available as the ceiling slants up. The puzzle stacker is awesome. I got mine at a garage sale, but I have seen them at teacher supply stores. I use bins for legos and other toys that need to be sorted. My grandkids love Geotrax. They seem to appeal to wide age range. 

 As you can see we also store our buckets of wheat here, otherwise there would be tons of space on this side of the closet for more storage. It works well to stack the large toy pieces on top there.

But here is the finished result.
