this morning i read about a new adhesive tape that works with the same mechanics as a gecko's foot. the economist article is subscription only, but worth it if you can get to it. read more about the tape that theoretically will allow a human to climb walls (much like spiderman and geckos) on this link that i will post as soon as my computer gets back to normal, because right now it won't let me open another window to look for the link....grrr...
