Great passive program: a board with strings in a grid, paired with a bucket below full of plastic bottle caps! It's like a very low-tech litebrite. a fun way to recycle and to make beautiful art :) From the Hillsdale (NJ) Public Library.
Another way to do a "blind date" without the work of wrapping books or folding stars - just a simple random book match method. These type of displays are a great way to move backlist titles that can be easily overlooked!
