top 10 must-have iphone apps (zz from CNN)

1. Crazy Disco

Price: $.99

Developer: Ezone

What it does: Revitalize the dullest of office parties with this rotating, sparkling disco ball, advertised by Ezone as a "great conversation starter." But there's more than one way to get down: developer Aaron Berk sells a rival app called "Disco Ball."

2. iBeer

Price: $2.99

Developer: Hottrix

What it does: This clever app serves up a never-ending brew - tilting the phone causes beer to drain out, and shaking it creates foam. Sober iPhone users can purchase iMilk or iWater instead.

3. iLightr

Price: $0.99

Developer: Ubermind

What it does: The Seattle based developer boasted that it had created "the most realistic virtual lighter experience available for any mobile device." You can brag about your phone while waving it over your head at a Journey concert.

4. Kazoo

Price: Free

Developer: Chudigi Software

What it does: A shiny green kazoo can play the scale in all of its shrill, buzzing glory. Think of this app as human repellent.

5.Koi Pond

Price: $0.99

Developer: The Blimp Pilots

What it does: Users find Zen by filling their screens with peaceful, customized koi ponds. More disruptive types can drag their fingers around to produce ripples and freak out the fish.

6. MixMeister Scratch

MixMeister Scratch

Price: Free

Developer: MixMeister

What it does: Amateur deejays can use their fingers to scratch beats over any song available. The sound effects range from "hip hop beats" to "the atomic bomb."

7.

More Cowbell

Price: Free

Developer: Maverick Software

What it does: Show everyone you're a "Saturday Night Live" fan by making your phone ring like a cowbell. Actor Christopher Walken immortalized the sound when he played an overzealous music producer who kept requesting more of it.

8. Rimshot

Rimshot

Price: $0.99

Developer: Sprikit

What it does: Download this app to play a "badum" or "tssss" sound effect the next time you hear a bad joke. But know that using cell phone software to mock someone else's wit could backfire.

9.

Sim Stapler

Price: Free

Developer: Freeverse, Inc.

What it does: For those who love the metallic clang of a stapler (or would like to envision themselves stapling a coworker's fingers), there's Sim Stapler. You can get it for free, but you'll never recover the time you'll waste on clicking on a fake stapler.

Wooo Button

Price: Free

Developer: Aaron Berk

What it does: For the many situations in which a man shouting "Woo!" is appropriate, there's this free app. Forty thousand people downloaded it in the first three days after it appeared.
