Examples of the posters made from the BlockPoster site. The MCG (with 30cm ruler at the side)
I also tried out a much larger size. From the example below I printed each page with a border. I guillotined one side off and used the other to glue the pages together, as above. You could use separate sheets and work on a display in a mosaic style. I pinned these page up quickly but this morning quite a few students had a good look at it and found it interesting.
