Peter Hosey, a Mac developer and author of ClickToFlash, writes about C, Mac software and old hardware.
Commenters recommend his pointers-in-C tutorial for refreshing and learning pointers, and link his ClickToFlash write-up.
When graphical gimmics steal the show: https://boredzo.org/pointers/boxes.png visualizes both pointers and their target (an integer) as 3d boxes. So the sizeof(int) is the edge length of this target?
Normally we see such guiding images with 2d boxes. There's nothing wrong with 3d because clearly, integers are also not 2d (they are not even 1d). However, don't associate the size of theses boxes with the memory size of an element. This overstresses the analogy and suggests the whole thing is a vector space, but it isn't.
For Mac OS X you have clicktoflash for blocking flash but it isn't a browser add-on, rather a plugin (similar to Flash, Silverlight etc.)

I'd love to see a similar plugin on Linux for Firefox, Chromium etc.

The author of this article had put up a whole post on pointers in c which to date is what I use to refresh my memory. https://boredzo.org/pointers/
This along with the pointers by Nick Parlante helped me get over my pointers Heebie-jeebies. http://cslibrary.stanford.edu/102/PointersAndMemory.pdf
Oh, wow! This is the creator of Glypha (https://boredzo.org/glypha/). I spent countless hours playing that game in the mid-ish 90's. Like so many games back then, you could tweak things with ResEdit. Nobody would believe my high score because they knew i could modify it.
Might it be this?: http://boredzo.org/pointers/

Another tutorial about pointers that I found quite nicely written is http://boredzo.org/pointers/.
