I've just released GPE Life 0.2. Changes since 0.1 are limited to a fixed .desktop file ("Conway's Game of Life" was too long, so it's just "Game of Life" now).
I've also taken a couple of screenshots:
Desktop icon.
Running. A couple of still life objects and two oscillators.
Paused. Activating some more cells.
The R-pentomino after some generations.
