CakeMark

Cutting birthday cake is an engineering challange. You need to cut this cylinder shaped object into N equal size and shaped slices.

I think we can print an indicative color strip on the base of the cake (not really on the cake, but the cardboard base portion of the cake box). Different bands tells you where exactly to cut for 4/5/6/7/8/9/10 ... equal sized pieces.

Lightstick Motion TVRemote

Instead of point and click, Lightstick Motion TV Remote requires you to wave light sticks in certain pattern to signal your TV (which has a camera installed as the remote reception) in order to perform TV control, like volume adjustment and channel flipping.

Good for couch potatoes who wish to have an reason to excercise, or kids who is dying to become an aircraft-carrier deck crew.

Chopstick based Human-Computer interfacing

Chopsticks is one of the most minimalistic device, yet its usage is so versatile. I think the possibility of using chopsticks and touch screen to replace mouse based human-computer interface would greatly enhance the user experience.

If you consider each window/item as object floating on desktop, using a pair of chopsticks you can:

"Pick up" an object ;
"Poke" a button;
"Squeeze" or "Strech" an object to resize it;
"Flip" an object;
Use one stick to "pin down" the center and the other to rotate an object around it;
"Merge" two objects together;
"Split" an object to two;
I believe there are many other possibilities.

Unprint

How many of your printed documents are actually not required? How many of them are either draft/contains typo/ill formated/incorrect pagenated/only need to read once/never collected?

We should have such a printer that has an "Unprint" tray. Just put fresh printed document in this tray, and the printer sucks it in, strip off the ink and returns white paper into the paper tray.

LapSpider

I was fustrated that I could not use my laptop in bed in a comfortable position. Putting the laptop on the lap, it is too low. If you use a cushion, the laptop will heat up pretty fast, and your legs can't move freely. The ideal thing is something like a breakfast tray, and it need to be tilted at the right angle, yet very portable.

The LapSpider is basically a foldable supporting rack for your laptop. It unfolds into a four legged thingy, with a bare-minimum top surface for you to place your laptop. The front and back legs are of different length, so it gives a proper tilt. Once fold up, it is the size of a clothhanger.

Never let your shirt ride up your back again

I believe quite a lot of guys have the some problem I have with shirts that are tugged in your pants: they are bound to ride up your back. I can't remember how many times a day I have to adjust it or tug it in again. Interesting enough, guys in movie seems never have such problem. Their wardrobe staff must have them glued on their pants.

The Shirt Garter is my answer to this problem. By clipping the front of the shirt to the tail of the shirt with a elastic band that goes between your legs, the Shirt Garter will effectively connect the front and back of your shirt, so when you bend forward, the front of the shirt goes deeper into your pants, while the shirt-tail pulls out more. Once you stand straight again, the front gets pulled out while the tail is automatically tucked in.

To make the wearing more comfortable, we will also produce a "Premium" edition, which come packed with a bottle of Teflon spray to apply on your genital area.

Cocktail Statement

Inspired by my friend's recent blog entry on Cocktail party guide, these cocktail glass/flutes make the ultimate statement in a cocktail party: you are not here for the drink, but here for the mingle.

The lady's version has a series of holes around the rim. The gentleman's version has jagged edges, as if it is broken. Both are sadistically un-drinkable.
