Great idea! reminds me of another project that used IR leds behind a blank canvas in an art gallery.  When people go to take a picture of "what junk passes for art these days" the secret "painting" is revealed.  This is really cool either way, I was just thinking merging the two would be interresting.

Thanks.  Would make a great scrolling sign that shows what FM channel I use for the music I play with my blinking Christmas lights.

The RGB modules look really nice too.  Wish I had the time.

Novel use of a LED array.  Nice that Allied provided part numbers for the bits they do supply.  But it would be useful if the supplier of the non-allied parts were also part of the article.  Especially considering that the LED array is fundamental to the gadget.

I like that idea, yes agree power cord is not ideal for this kind of application. The other option here would be battery power.

You know what would be fun?  Hang a weight on a rachet (like a pendulum grandfather clock) to spin a motor/generator to provide the electrical energy for this circuit.  Lose the AC mains line cord running up the wall.

This looks like fun.  Great idea for waiting rooms.

This looks like a fun thing to come up with and to do. And the images or words can always be changed when you get tired of them.
