You are currently using a browser that is incapable of displaying the default layout.
The Legacy Vault is intended to work on as many browsers as possible. From the latest, to the oldest. (Within reason)
These layouts are crafted based on different eras of the internet. Not only to work on Internet Explorer 3.0, but to also provide a more seamless experience when browsing on retro hardware! Seeing modern web design on retro hardware is jarring, to say the least.
Depending on the platform and technologies capable of being used on said platform (And given you are willing to have any of this set up);
You can expect to see any of these technologies in use on any of these layouts.
I do not recommend using any of these on an unsheilded connection. Or on a device you do your banking on.
If you'd like to try any of the other layouts on a modern browser: Here's what I cooked up!
