Explay was an Israeli start-up focused on Pico Projectors, and were bought by ADM (for only $555,000) towards the end of 2009. Explay were working on a pico-projector module , but also wanted to make standalone projector (to be called the OiO) - but it's not clear whether they are still working on that.
In September 2010, Explay announced that their modules are now shipping to customers, and they expect products at around February 2011.
