What’s Coming Up Next? – Tom Bluewater Introducing Oh My Rainbow for Mac OS X

Mac OS X software Oh My Rainbow

TOKYO (MacHouse) – The other day, I was looking at some desktop applications at AppShopper. And I ran across an application named Rainbow, which made me think to myself “Hmm… A desktop application for creating a rainbow?” Actually, it is not. I guess it’s a desktop application that comes with several graphic filters. So I thought to myself “Can I develop a desktop application for creating a rainbow?” Why not? I thought I could do it in the same way I developed TextAround2. As a result, I submitted a new desktop application to Mac App Store several hours ago. This new software submission is called Oh My Rainbow.

Oh My Rainbow is a simple desktop application that lets you create a rainbow as a picture. Yes, you can do it if you have Adobe Photoshop. And, yes, you can do it without spending $19.99 a month if you just have this application. All you have to do is 1) to pick several colors and then 2) to configure several settings. And voila! You’ve just created a rainbow. And you are just a couple of steps away from saving your rainbow as a picture.
