Various researchers have built their own systems by combining a DLP projector with an LCD display with it's backlight "hinged" out of the way, a la the original paper by Seetzen et al:

Seetzen, Helge, W. Heidrich, W. Stuezlinger, G. Ward, L. Whitehead, M. Trentacoste, A. Ghosh, A. Vorozcovs, "High Dynamic Range Display Systems," ACM Trans. Graph. (special issue SIGGRAPH 2004), August 2004.

For my own use, I still have the HDR viewer I made over a decade ago:

Ward, Greg, "A Wide Field, High Dynamic Range, Stereographic Viewer," Proceedings of PICS 2002, April 2002.

By far the easiest (and cheapest) solution for still images is to print out a grayscale version of the square root of your image (with maximum normalized to 1.0) as described in the above paper, but as a large-format print. I would make this one the image with exaggerated contrast, since you can print it at high-resolution. Then, project the original image divided by this grayscale image using a standard DLP or LCD projector -- preferably a bright one although it doesn't need to be high-resolution, onto this print. Line it up, and violá! You have a high-resolution, high dynamic range still image. There's no way to make it move, sadly.
