Conway's Game of Life, retro edition

Here's another addition in the line of retro-styled games, implemented using obsolete technology. Conway's Game of Life isn't really a game, but it's neat, and so we thought we'd implement it in Visual Basic 6, the last version of the Visual Basic family of languages that compiles to native 32-bit Windows executables.

How does the game work?

Start the game. Select a few cells to modify their state. Click run (that's Game > Run, or C-r).
