Down near the bottom of this page, you'll find Bill Bowden's Fading Eyes. It's a fun, easy project, and you can use a couple of 741s instead of a 324 (which is a quad op amp).
 
are there any other experiments....even that one is nice...i want to make it...but i want a few more options.......just 4 fun....:)
 
My son and I built a "light-listener" which was a 741 with a cadmium sulfide photocell as the input - followed by an LM386 audio amplifier (though you might power an earphone without it). With it you could "hear" the output of TV remote controls, the buzz of fluorescent lights, the flicker of a flame, etc. That was a long time ago. I've been tempted to construct a more permanent version.
 
sir where can i get the circuit diagram and explanation for ur "light listener" project.It seems very interesting.I want to do and enjoy it.Can u please help me???
