Fibonacci Zoetrope Sculptures

Stanford design instructor John Edmark has rethought the zoetrope with beautiful 3D-printed sculptures that animate when filmed in sync with a strobe light.

Explains Edmark:

These are 3-D printed sculptures designed to animate when spun under a strobe light. The placement of the appendages is determined by the same method nature uses in pinecones and sunflowers. The rotation speed is synchronized to the strobe so that one flash occurs every time the sculpture turns 137.5º—the golden angle. If you count the number of spirals on any of these sculptures you will find that they are always Fibonacci numbers.

For this video, rather than using a strobe, the camera was set to a very short shutter speed (1/4000 sec) in order to freeze the spinning sculpture.

In the early days of developing this technique, Edmark created some stop motion tests to illustrate how Fibonacci tiling works in conjunction with animation:

The festival kicks off next month

There’s a dazzling projection art event coming to Sharjah.

Sharjah Light Festival is returning for 2022 with 11 nights of colourful projections and music. If this year is anything like previous festivals, our eyes are in for a treat.

The colourful festival is the first and only of its kind in the region and has been running for over ten years. It attracts thousands of visitors to up to 20 locations in Sharjah each year. The designs are inspired by local culture, stories and traditions.

The 2022 Sharjah Light Festival goes from February 9 to February 20 and is organized by the Sharjah Commerce and Tourism Development Authority.

The festival brings a kaleidoscope of creative lights and colour to Sharjah’s architecture. Diverse locations are featured during the annual show, with light and sound spectacles that transform them. (Have your camera ready.) The festival uses energy-saving lighting technology and all the lights and projectors used have passed certification for environmental compliance.

The Sharjah Light Festival also showcases the emirate’s rich heritage and historical monuments. Local and international artists, musicians and light technicians collaborate to showcase the emirate’s achievements.
