There is a guy in Alberta who has designed a lot of patterns using the disappearing technique.
(sorry, I can't find a link right now)
Though when I read his blog, I realized you could turn most any quilt block into a Disappearing pattern ... you just needed to experiment and try it out. I remember his blog ... he'd show a traditional, then say "what if" ... then he'd go a step further with another "what if" ... and then the creativity was rolling, and another "what if".
Go for it ... and create your own!
