We present a design for a hard X-ray all-sky monitor which consists of
a spherical structure whose surface is partially covered by circular
units which serve the dual purpose of detector and mask elements,
forming a coded aperture telescope with full steradian
coverage. We demonstrate that a simple practical implementation of
this geometry results in an instrument which is capable of measuring
the fluxes in the 10 -20 keV bandpass of the hundred brightest
sources in the sky at least every two days. We also show how this
instrument can be used to image burst and transient sources; obtain
their positions with arcminute accuracy; and follow their light curves
throughout their lifetimes.
