I found a couple of places that host scripts for an Amazon Wishlist Display. There is Kalsey.com Amazon Wishlist display which puts out a text list of all Amazon products in your wishlist. Here is a quick rundown of the idea from Kalsey
MTAmazon is often used to insert a person’s wishlist into their page. If you don’t want to go to the trouble of installing MTAmazon to display your wishlist, or if you don’t use MT, here’s simple way to put your wishlist on any web page.
Go to Kalsey.com for instruction on how to impliment it.
The second script I found is from EDazzle AmazonBox This wishlist outputs pictures of the items on your list and is extremely configurable with lots of CSS tags to help integrate it into your site. See how it works at Mindful Musings
