Do such things exist? Just want something for my students.

Like wooden blocks with strings that you can use to connect them to the next and/or previous node? I've never seen such a thing, but it would certainly be cool.
I found at uni, the easiest way was just a powerpoint presentation. Use pages to show the nodes, and animate the pointers and how they work.

Is that your way of saying "I'm a college dropout"?

I made a bunch of data structure animations in Logo and Turbo Pascal long ago. A little stick figure would move a box off the stack when you hit the POP button, or laboriously do all the steps of (+ 2 3) like a warehouse grunt. I sold it to IBM who, at the time, were training their blue collar workers to program rather than lay them off. It was a big hit, with the added bonus of being written in a beginner's language.
I have no idea where the discs are now, though. A programming teacher like yourself shouldn't have any trouble making your own. Logo is all about that kind of graphics.

P.S.
Python also has turtle graphics, if I recall correctly.
I was thinking of something more physical. This isn't a lecture class I'm doing.

We covered stacks already, I found a suitable demonstration in the cafeteria.

Draw the boxes on the dry erase board like everyone else.

Use the students to model the list. Give them cards with both a piece of data and the name of the 'next' student. Or have sex with them and post pictures to /b/.

Seconded on the mantrain idea. If you really, really think about it, that really is the best metaphor you can use.

Jesus. You really think you need a freaking modelling kit to explain linked lists? If your students' attention span is that pathetic there's no hope for them anyway. Draw this on the blackboard:
*---> *---> *---> *
and that should be MORE than enough visual aid.

When I had to explain them to my friends, I drew something like:

Ha ha ha ha. Perfect.
The term pareidolia, referenced in 1994 by Steven Goldstein, describes a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant. Common examples include images of animals or faces in clouds, the man in the moon, and hidden messages on records played in reverse. The word comes from the Greek para- — beside, with or alongside — and eidolon — image (the diminutive of eidos — image, form, shape). Pareidolia is a type of apophenia.
There have been many instances of perceptions of religious imagery and themes, especially the faces of religious figures, in ordinary phenomena. Many involve images of Jesus, the Virgin Mary, or the word Allah.
