VJBrisk is a small .exe file that can be used to replace another .exe.

Example: If you want to change your Stocks.exe application and make it launch VJEschaton.exe, but Stocks.exe is somehow hardcoded into a skin or application, then rename VJBrisk.exe to Stocks.exe, and drop the new Stocks.exe into the correct folder. VJBrisk will then allow you to launch whatever app you want to, instead of Stocks.exe.
