Roll or two of aluminum foil, scotch tape and a needle. Tape foil on outside (or inside if there's no way to reach outside) of windows safely. Once up, scratch little triangles with the needle to let in some light that's filtered. Worked wonders on my south facing windows when I lived in NYC without air-conditioning. Rips off easily when you want winter sunlight. Or, I suppose you could put up white plastic contact paper to reflect light and cut out stencilled designs if you want something a bit more regularly and artistic.
