Shift and tilt adapters

[eitanwaks]

Have contemplated moving to large-format photography specifically for movements in cameras.  I have gone to the conclusion that large-format photography is not for me because it would be exclusively tedious and it difficult for me to operate the camera.  I would still love to use movements with my cameras.  I seem to remember reading about some type of adapters that I can fit on the camera to which I can connect the lenses.  This adapter had to shift and tilt movements.

Are there shift and tilt adapters available for Mamiya RB67?

Thanks,
