It's a slide! It's a bookshelf! It's a castle!

I think this is ingenious! A play structure and bookshelf rolled into one. This is by Koichiro Hoshino. My inner child is a-calling!

More cool pics after the break!

Of course we want to go down that slide! I'm loving those little rolling blocks down at the lower right!

I think this play structure packs a lot of punch -- look at all that shelf space!
