2. make a wooden box with a plexi-glass (or real glass) front.

This reminded me... now that it is winter and time for an indoor
project.... I want to make a fish periscope. My ponds get so much plant
cover that it is hard to view the fish. I was thinking of making a
decorative pond periscope to view the fish. Maybe add some bright LED
lighting... has anyone done this or have any experience with this type
of idea?
