We describe a novel system for focusing X-rays based on the eye of a lobster and a method for fabricating such optics using microchannel plates which have pores with square cross sections. Lobster eye optics will enable us to construct X-ray telescopes capable of simultaneously viewing a large fraction of the sky, making possible a new class of X-ray astronomy survey and monitoring missions. We have tested the X-ray optical properties of one of the first available square pore MCP's. We find that the angular resolution of the MCP lense is 5 arcminutes (FWHM). The resolution is limited by misalignment of the pore surfaces.
