Submission + - Vibrating display enhances visual quality (acm.org)

mutherhacker writes: Scientists from the University of California, Berkeley and the Hebrew University of Jerusalem have created a display that enhances the displayed image by applying small-amplitude vibrations to the display panel and synchronizing them with the screen refresh cycles. The display works with a weight attached to a motor that spins at 1800 RPM. Results are quite impressive. The article is paywalled but the abstract is very informative. A video is also available.
