NISHIO Hirokazu

This page describes about my artwork 'Virtual Star', which awarded on ASIAGRAPH 2009 as an excellent work. It was Exhibited on National Museum of Emerging Science and Innovation (Miraikan) at Odaiba, Tokyo.

In this artwork, there are a lot of circles. Circles only. No lines. However you will see a lot of stars. Those stars are not drawn. They are virtual stars.

It is a form of visual illusion, such called illusory contours or subjective contours.

Motivation

I'm doctor of science and I want to show you the beauty of mathematics.

You may heard about golden ratio:

φ = 1.6180339887...

The number has very beautiful property:

1 / φ = φ - 1.

You can easily confirm it with a calculator. 1 / 1.618 becomes 0.618 and 1.618 * 1.618 becomes 2.618.

I used this ratio to determine where and of which size circles are drawn.

This is the reason why those circles make you see virtual stars.

How to see the artwork

I released iPad/iPhone apps Virtual Star Clock FREE and Virtual Star Clock.

If you want to buy physical version, please contact me by e-mail < nishio (dot) hirokazu (at) gmail (dot) com >. It is made with photo-acrylic printing, which is a technology used to display photographs in museums.

420mm x 594mm, 200 USD.

If there are no limit to budget, I want to create new version with Iron(II,III) oxide and gold. They are very stable and will last handreds of years, so suitable for mathematical beauty.

2012-04-28 iPad/iPhone apps 'Virtual Star Clock'

Released Virtual Star Clock FREE and Virtual Star Clock.

Description on app store

The artwork of this clock is derived from my artwork 'Virtual Star', which awarded on ASIAGRAPH 2009 as an excellent work. It was exhibited on National Museum of Emerging Science and Innovation (Miraikan) at Odaiba, Tokyo. Of cource most of people didn't go the exhibition, so I made this app as a popular edition, such like postcards sold on museum shops.

2011-10-26 A2-size photo-acryl version

A2 means 420mm x 594mm. I decided to fix circles' line width. I think it is better to show concept.
