One commenter in the youtube asked if the amount of shift is significant for use or not - is it, for architectural use with a wide lens?

Great tutorial - I have to admit that I didn't know we had this feature. Something new to play with without spending any money!

I've been playing with this for a bit, it seems like it could be useful. What does that "angle" setting do, does it actually change the angle of the sensor inside the camera?

It rotates the sensor, no tilt unfortunately.

Pentax has all the pieces available to create the same type of ultra high resolution shifted images as Hasselblad.They can shift the sensor, even rotate the sensor, taking multiple images with a 1.5 pixel shift, and then combine them together (in camera HDR processing). Thus an APS-C sensor based camera becomes the ultimate high resolution landscape camera with exceptional color accuracy. Using this approach, the K5/K5II/K5IIs/K30 could produce 64MP images in this mode.

Actually if Pentax applied this in a similar fashion as bracketing, just take and store the 4 or 6 images (as RAW or JPG) and let post processing perform the stacking, would certainly provide a much higher quality result. Just tag the EXIF with the amount of pixel shift and direction, and the stacking would be easy and quick.

Very cool. I am impressed with the amount of shift available. The big question in my mind (likely to be answered in a followup video) is whether the amount of available shift is less with those DA series lenses that have minimal coverage.
