An iPod full of diverse games on this week's Mobile Monday. My personal favorite happens to be TonePad. Mostly because I like messing around with sound without, you know, actually accomplishing anything or learning real musical skills.

Diorama - Like the classic Labyrinth game where you roll a ball around a level, only this one has a remarkable 3D perspective that changes as you tilt the iPhone. Navigate narrow bridges and roll through hidden tunnels to reach the goal. Also included is a stereoscopic view that allows you to view the game in 3D with the correct eyewear. There's no sound as of now, but an upcoming version will fix that.

Kaloki Adventure - A slightly trimmed-down version of Outpost Kaloki that works wonders on the small-screen. Kaloki Adventure is a delicious casual strategy game that will remind you of Lemonade Stand. And not just because you're selling lemonade in the first scenario (fact: all alien species love lemonade). Upgrade arms of your space station with various shops to supply travelers with what they need. Power stations are needed to keep things running, and you have to find a good balance between selling cheap goods and expensive treasures, otherwise your customers won't part with their space cash. A free Kaloki Lite is also available.

TonePad - Did you play Andre Michele's ToneMatrix featured on a previous Link Dump Friday? If so, you know exactly what to expect with TonePad. A grid of dots fills the screen, and all you have to do is tap one to fill it. Every few seconds a wave sweeps along and plays each lighted circle. The higher the filled dot on the screen, the higher the pitch. Create some seriously catchy sound loops or just see what a smiley face would sound like. You can even save, load, upload and download songs! TonePad is free, but TonePadPro allows you to use your creations as ringtones.

Trains - A simple game of directing incoming trains to their color-coded stations to unload cargo, and then directing then safely away again. Just tap on the track intersections to change orientation and direction for the trains. Some trains are longer and worth more points, some move faster, and all present a challenge that is quick and easy to pick up and play. If you enjoyed Flight Control, you will find a lot to enjoy with Trains as well.
