Ken Burns View

I thought it might be fun to highlight a past control of the week on occasion, in case you might have missed it the first time around. This week, check out this awesome Ken Burns View control, authored by Javier Berlana, and originally featured back in November of last year.

This control lets you create a slideshow that uses a Ken Burns effect to transition between different images. This control is made available under the MIT License.
