gpuViewer starts with the view of your collection grouped by year photos were taken. You then use the mouse wheel to zoom and see more of what you’re interested in.

When the box for a year is large enough, it gets split into months.

The months themselves open up into days

Days with many pictures get split again, based on the time of shooting

Selecting shots becomes a simple matter of dragging the mouse

Zooming can continue down to 100% level (and beyond, actually)
