    Abstract: A system for casting cement uses a plurality of lightweight forms made from a ladder-like, aluminum member covered on one side by a sheet of transparent plastic. The forms may be assembled and erected in any desired and suitable shape or configuration. As cement is poured, its surface may be viewed through the transparent plastic to find and correct surface blemishes. A series of connector and optional connection points enables the system to be used in many alternative ways.
