iPhone: Ever thought about using your iPhone as a musical instrument? Well, now you can thanks to MiniPiano. The app includes just one octave of a keyboard, which you can play simply by touching the keys on the screen. The keys have been gorgeously recreated and the full-screen keyboard is very easy to play (in the sense that the keys are touch-friendly, not that it will make you sound like Beethoven).
Mac: Tools like iPhoto and Picasa have their place but they are somewhat bloated, and can slow down your viewing experience. CocoaSlideShow is a simple, free and fast program for viewing your photos on Mac. Simply fire it up, enter a time interval you want between each slide and sit back to enjoy your photos. You can watch slideshows in full screen and also edit EXIF and IPTC metadata.
Windows: Armalyte is a great update of an old Commodore 64 shoot ’em up. Sideways scrolling through space, facing an onslaught of enemy wave, punctuated by boss fights. It’s been done hundreds of times before, but Armalyte is a particularly good example of the genre. May make older gamers seriously nostalgic!
