I have a list of blogs I follow. One of them is Lifefeast by Ana María Menezes, it is full of ideas and excellent posts. She mentions some glogsters, created by a Bulgarian teacher,which are really worth seeing. She presents vocabulary lists or grammar items in a very creative way using glogsters.
This one is about food:
Another one about the farm:http://sunrise651.edu.glogster.com/on-the-farm/
