Watch for this item, it's on my eBay shop and will soon be on the HornbostelProductions.com shop as well.  It's a modern museum structure in realtime 3d, in the Unity 5 engine.

The idea is as follows:  The winning bidder sends a predetermined number of pictures or photos to me, some mix of landscape, portait, and square shape, and I drop those photos into the level to replace the 'Placeholder' textures.  So it is a customized 3d art gallery of your family photos shipped to you on DVD for $3.99, the current sale price on eBay.
The DVD includes Mac, Windows, and Linux installers - 32 and 64-bit.
Other options might be included over time as well, like changing the wall colors (red, blue, dark green, pastel green, tan, dark brown, cyan, ochre, white, black, pink, orange, or purple) the sky texture (sunset, night, or day) and changing the text on the banner or sign hanging over the entrance.  (There's no banner in these screenshots just as there's no glass in the windows, but the glass is implemented already and there will be banners in the future.)

There's also the possibility of filtering your photos to make them look more like they belong in the gallery - if you want them to look like paintings I can do that for you using Akvis ArtWork, a program that has one of the more realistic looking paint filters available.
