What goes around keeps going around and around ...
"Jim Lewis, known among computer buffs as the driving genius behind the popular InfoSelect personal information management software, appears consumed by the ancient quest for a perpetual motion machine.
The prototype is a sleek gyroscopic top that testers say will spin for an unprecedented 15 minutes when started with a single flick of two fingers.
The contraption uses a system of balanced air chambers and other tech tricks to take a flicking and keep on spinning. At prices between $49 for brass and $2,500 for gold, Lewis' Quark top is available at www.miclog.com.
On a holiday note, it also comes in a dreidel version, which is guaranteed to drive kids nuts as they wait for it to stop while playing the traditional Hanukkah game."

Quark High-Performance Top
"Description: That's right--it's a top, but unlike any you've encountered before. The heavy brass rim is mounted low, and the mass is concentrated at the outside. You do the final balance tuning yourself with tiny weights and an included laser pointer. A twirl of your fingers sets it spinning for as long as 15 minutes! The designer, Jim Lewis, is the creator of the renowned PIM, InfoSelect. High-precision machining is his hobby.
Cool because: You can initiate serious discussions about Mass Optimization Horizons.
Downside: People will mistake your frequent explorations into the physics of rotating objects as mere child's play. But You won't let a kid anywhere near this technological treat."

Spinning top gets 15 minutes of fame
Quark toy will keep you entertained for hours on
The pitch was one I hear pretty often — just give us 15 minutes of your time. But 14 minutes, 35 seconds was all I needed to determine that the new Quark top lives up to its advance billing.
INVENTOR JIM LEWIS claims the precision-designed toy performs 10 times better than practically any spinning top on the market, and certainly it outperforms any simple wooden top or even the best toy gyroscopes, which typically spin for up to 5 minutes. Without much effort, the Business & Technology team here at MSNBC.com was able to get the two-ounce metal-and-plastic Quark spinning on its tungsten-carbide tip for more than 10 minutes on average, and several times we approached the holy grail of 15 minutes claimed by publicity materials. Often the top would wobble and appear to be on the verge of falling — only to straighten itself and continue spinning for another 5 minutes or more. (The best time we could achieve in intra-office competition was 14:35 minutes.)
In addition to calculating the proper “mass optimization horizon” where the material switches from plastic to metal, Lewis came up with a unique method for users to individually balance their new top using a tiny laser-beam pointer, adding several minutes of spin time. He has applied for several patents.
THE ART OF SPINNING
The whole process took me about 20 minutes to achieve what I considered “good enough” results. To improve spin times, I could rebalance the top using even tinier metal washers included for fine adjustment. At $49.95 for the entry-level brass version, the Quark is not for young children but would be right at home in the executive suite alongside the silver clacking balls and desktop dartboard. A tungsten version, which can spin for more than 20 minutes, is $149.95, and a $2,500 solid gold version is available on demand.

We're long past the era of the dot-com office foosball table, but toys are still crucial to proper corporate function - in fact, Micro Logic's Quark Top (www.miclog.com) serves as not only a hyper-nerdy desk tchotchke but, if you play your cards right, as an office productivity enhancer. The flywheel-weighted precision top, made of brass and tungsten carbide, is designed to spin and spin and spin; if you really set about tweaking its performance, using the included laser pointer, shims and weights to perfect the balance and tilt of the mirrored spinning surface, it'll go for about 15 minutes, making it a fine meeting timer. At $49.95, you may, therefore be tempted to make this one an office-supplies expenditure. Good luck.
