Looking for ‘Wish list’ sidebar slider widget

I want to display a slider widget on my sidebar with links/images to things I am currently shopping for on other websites. For example: http://wishwishwish.net/ has one on her sidebar under ‘The Wishwishwish list’. I have done lots of searching but can only find plugins related to Woocommerce or selling your own items on your site. I am not interested in selling anything on my site, just want to show links to things I am shopping for.

Thank you!
