Ephemeron Industries

Ephemeron Industries has been doing a significant quantity of contract software (and hardware) development for several years now. We decided to finally put up a page clarifying that. See our contracting details for more information. No project is too speculative!

Jigsawed 1.2 - adds user-requested enhancements.

• Now there are multiple background colors (and pictures).
• You can adjust how forgiving the piece-snapping is.
• You can save your favorite puzzles for easy access later.

Jigsawed 1.1 - has been released with many new features!

• You can build the puzzle gradually by snapping together matching pieces into groups, then moving and combining groups.
• Jigsawed now keeps track of your progress. Completed puzzles appear with green or yellow checkmarks in the image browsers depending upon whether you completed the puzzle alone or with help.
• You can now "Start Blind," and the puzzles will come pre-shuffled so that you don't know what the picture is like until you've completed it.
• You can now click "Random" to get a puzzle you haven't yet completed at random. Combine this with "Start Blind" for extra fun.
• Bug fixes.
• Loading saved puzzles is now 3-10x faster depending on the size of the puzzle.
• The puzzle dividing lines now fade out when the puzzle is complete so that you can get a better look at your accomplishment.
• Localized in both Dutch and English. The Dutch version searches Flickr in Dutch too.
