Apps using Grand Central Dispatch and/or OpenCL?

So, it's now close to a year since Snow Leopard was released. Anyone know of any apps using Grand Central Dispatch or OpenCL yet? Are Apple's own apps even using these technologies?

Theoretically, GCD and OpenCL are awesome, but if nobody uses them...

 

Doh! Never mind... should have searched first
