What’s Coming Up Next? – MacHouse Introducing MakeCheckerboard for Mac OS X

Mac software MakeCheckerboard

TOKYO (MacHouse) – It’s been more than 10 days since we released the last software title. Just about half an ago, though, we submitted the fourth software release of the month to Mac App Store. This new release is called MakeCheckerboard.

MakeCheckerboard is a Mac desktop application that lets you create and save checkerboard (alternating square tiles) as image. You can set two alternating colors as well as dimensions of square tiles. These alternating colors don’t have to be 100% opaque (not completely transparent). So you can control each color’s opacity level on the color picker panel.

MakeCheckerboard is a very small application. The file size is about 740 KB, probably the smallest of all Objective-C applications we’ve built over the last eight or nine months. That doesn’t mean it was easy to program. In fact, we faced some difficulties partly due to Apple‘s sandbox restrictions.
