I have built a few tables using FTIR and DI. Done some experiments with capacitive multitouch sensing (similar to SmartSkin) with positive results. Experimented with various micron wire grids in order to minimize its visibility in front of the LCD screen.

Currently exploring other multitouch sensing concepts:

-- Improved version (higher resolution with less HSDL-9100 sensors) of ThinSight for IR proximity sensing behind the LCD screen
-- IR laser beam application (LLP) for large low-cost multitouch displays for interactive art installations, storefronts, shopping and social interaction.
-- WPF based UI multitouch framework
