LED Pen

This might look like a normal wooden pen, but it's not. It's a pen with LED light, which measures the cm, inch, mm, feet etc you just wrote.

This is a nice toy for everyone, but it's especially made for architects, artists and engineers that need to measure everything very precisely in all different values.

It's cool because it's very easy to use, just switch the back of the pen to another value. This is instant gratification in its smallest form.
