The Geometry Junkyard

I actually like the term &quot;web pointers&quot; on the page over the traditional [hyper]links, as it&#x27;s more accurate to what happens in reality: The reference is one-way, without feedback on if what is being referenced changes or disappears entirely.<p>Case in point, I wanted to check out the &quot;escher in reality&quot; 3D models and got a 404.

So many dead links! Sad, I would love to poke around a resource like this.

I always liked geometry, but wasn&#x27;t particularly talented in it. Still, I wonder whether geometry could explain certain algebraic concepts much more intuitively, or even lead to new discoveries that would be extremely difficult to do using math symbols.

One of the pages talks about a problem he got talking to mathematician on sci.math. Where do mathematicians talk about math and collaborate on problems nowadays?
