Heap Inspector
This is a pretty awesome memory tool hobby project Jvander Beek of Vanguard Games is working on. I’m a big fan of the physical memory layout / fragmentation view. Take a look at the videos he has up on YouTube showing it off. He mentioned in the comments potentially releasing it to the public. I hope he does; I’d love to be able to integrate it with a few of my own memory tools and projects (assuming he makes it open source).
