Bonus behind-the-scenes photos
This is the good stuff right here. HAL Laboratory has a delightful little website with making-of photos for Kirby and the Rainbow Curse and a video showing how to create your own clay Kirby.
Between this, The Neverhood, Skullmonkeys, and The Swapper, I find myself wishing that more developers would pick up a clay set. These handcrafted games will forever feel special.
