Plushie is based on the Teddy3D software, which lets you create 3D models by using a 2D drawing interface. Plushie takes it a step further and simulates stuffing and creates a sewing pattern for you to make stuffed animals from.
They have a demo video on the page showing a workshop they did with kids designing and sewing plush toys. Definitely worth a look!
