Uzu bills itself as a “kinetic multitouch particule visualizer” which translates into really fun frickin’ fun interactive light show. By touching it with your hands you can freeze, move, contort, and change an explosion of multicolored lights through up to 10 points of contact. It doesn’t serve any practical purpose, but it’s probably the neatest app in the iTunes store right now that any iPad owner will use to show off the device’s “cool” factor.

From Uzumotion:

Points of light will shoot across the screen and fly to your command, twirling in a vortex of color and motion. Freeze and move Uzu in 3d space while contorting spirographic curves with your fingers. Uzu lets you quickly switch between 10 different modes of real-time animation by simply changing the number of touches you’re using. You can spend countless hours discovering the many unique ways of playing and interacting with Uzu.

Uzu is very happy when multiple people touch it. Uzu loves parties, children, music, cats, and pubs – although not necessarily in that order. Uzu has many plans for the future, but Uzu would like to hang out with you now if that’s cool.

It’s easier to see it in action than to describe it, so here’s a video from the creator. Althought it’s for the iPhone OS, right now it’s only available on the iPad in the iTunes store and is currently free for the July 4^th weekend.

Video conferencing sounds sexy, but it will be a while before the new iPhone makes it accessible enough to be a part of everyday life. As a small business owner, maybe it makes more sense to focus on things that will help you sell your product. GoToMeeting is a web conferencing tool that makes it easy to set up and lead web-based presentations or product demonstrations in a matter of minutes. Attendees watch in real-time on their computers what the meeting leader is demonstrating on their computer and GoToMeeting makes it simple to set-up appointments through Microsoft Outlook containing info like a link to sign into the meeting and a number for a group phone call.

They’ve recently released a free app for the iPad, so you can join a meeting at no cost. The iPad version is very nice as it allows you, somewhat out of necessity, to use the tablet’s built-in speakers and mic to talk in a meeting without having to use your hands to hold a phone. Another nice feature is the ability to pinch-in to zoom on content so you can get a clear view of what’s on the meeting organizer’s screen. Click below to get a quick video demonstration of the iPad app.

For online professional business networking, LinkedIn is still the gold standard. It recently topped 70 million users and has been adding a ton of new features including: deep twitter integration allowing you to follow your linkedin connections privately, tracking movement in industries by seeing recent hires and departures at specific companies, and integration with Microsoft Outlook.

This free LinkedIn iPhone app gives you access to much of the functionality of the site, allowing you to update contacts with your status, send invites, accept invites, message, as well as connect instantly with nearby LinkedIn app users with the “In Person” feature. Download the app for the iPhone here. LinkedIn also offers free apps for the Blackberry and Palm Pre.

As someone who uses their iPad primarily to keep on top of breaking news, trends, and analysis, there is no App that I’m spending more time with than NewsRack. It’s an RSS (really simple syndication) reader that allows you to keep track of updates from your favorite websites without having to visit individual sites.It synchs with an existing Google Reader account and has full integration with other apps and services allowing you to share stories through Google Reader, email, Facebook, Twitter, Delicious, etc.

I’ve got over 100+ subscriptions to feeds covering business, startups, entrepreneurship, technology, the media industry, culture, social media, and my neighborhood. Sure, Google has developed an optimized version of the Google Reader site for the iPad, but this app allows me to synch my articles and read them even when I don’t have an internet connection. It’s not a perfect app. Sometimes it does not appear to synch 100% accurately with Google Reader leaving articles that have been removed from Google on NewsRack. In comparison to Reeder, another RSS app that will be covered in the future, it downloads rather sluggishly. However, NewsRack provides a simple, clean layout that makes it easy to organize and scan large amounts of subscriptions. It’s especially ideal for an early morning commuter without access to a cellular or wifi signal on their iPad.

As of this moment, this is my favorite app for handling RSS. What’s yours?
