A tiny time lapse

Processing code for a time lapse application.
Tested on MacOS X and Windows 7.

The screenshots below are from the opengl version of the application. Processing application will be available soon.

virtual street seller

sinabey — Fri, 31 Dec 2010 10:32:33 +0000

Interactive Installation for the “Meeting Istanbul” exhibiton. This particular work symbolizes the way street sellers approach people; walk by to catch their attention, make eye contact to attract them.

Concept: Lauren ten Hoor
Implementation: Cem Sina Çetin

contact basket

iPhone application that prepares a mail message that contains the entire address book information. In addition, it uses this information for the game: “I can call you but I can’t recall you.”

fluid memory

sinabey — Sun, 27 Dec 2009 14:28:55 +0000

Fluid Memory is an iPhone game and an instrument. Same principle with “Simon”, the game is based on memorizing a series of notes and the associated buttons. Buttons are bubbles in water in this case, and the complete set of bubbles make up one octave. During game mode, the Fluid Memory works in rounds; game shows a sequence, then the user repeats it. if it the repetition is successful, then the game shows another, longer sequence by appending the previous series with a new note. Scoring is based on the number of consecutive successful repetitions and repeating speed. In free play, there are no rounds or scoring, every bubble is available to play and it is possible to play polyphonic tune within the range of an octave.

Fluid Memory is unfortunately not on iTunes Application Store anymore, because it was stated that using the word “memory” was a direct reference to the product “Memory”. “The sum of which was a 6-digit figure” was enough for me to step back.

retro snake

sinabey — Thu, 17 Dec 2009 01:00:36 +0000

“Retro Snake” is an iPhone application and my aim with it is to strip iPhone from it’s exotic features entirely. There are many remakes of classical games, yet iPhone’s capabilities are so appealing that, this usually ends up with effect overkill and spoils the game. Retro snake doesn’t have any colors, doesn’t have any sound effects, high score table has only one entry, doesn’t use multi touch or accelerometer events, just like any fully operational snake game 20 years ago.

musophobia

sinabey — Thu, 17 Dec 2009 00:01:19 +0000

Musophobia is a bug, a deliberate loophole in the rendering stage.

And thus, Musophobia is a highly unconventional painting application.

Instead of a single brush, you wield up to 999 particle-brushes at once. And instead of using the brushes, you can merely interact with them: set them in motion on different trajectories, force them to fall, orbit on random centers, spin around the point of touch, collapse into a cluster or, simply, disturb by touching them.

Particles can be modified to create different effects. Musophobia makes many options available, including changing particle size, color, recovery speed and interaciton sensitive options such as hue change speed or spin radius.

Motions of the particles are all decided by the modes of interaction, dependant on each mode’s function. Modes themselves also interact, override and manipulate each other to visualize unpredictable paths and dynamics.

Musophobia was never meant to be a user-friendly application.

It takes away the full control of the users and reduces them to one of many parameters those bring life to the particles. In order to create, it forces you to cooperate.

Musophobia is hard to master and most likely to frustrate.

shadow play

sinabey — Thu, 17 Dec 2009 01:00:55 +0000

In “Arts and Computing” Course, our aim was to produce a project, which is nourishes by both arts and sciences. To do so, every year, equal number of arts and computer sciences students enroll to this class and work in pairs. Pairs were chosen blindly and I had a very specific project in mind, so I did my best to work alone. I achieved that, too; thanks to the fact that odd number of students enrolled that year. Usually the term projects are in 3D and complex, so I was so excited about trying something different and keeping it as simple as it gets.

Shadow Play is a project by which I tried to find a different approach to traditional shadow puppetry. My aim was to create a system that makes it possible for a single person to build the entire environment and the dynamic figures. Dynamic figures would be butterflies, which move autonomously in the environment and interact with the static shadows.

Shadow Play was completed in 2008 and it was accepted to Siggraph Asia 2008 as a sketch presentation in Arts and Robots session. Detailed information is available on the one abstract of the project.

Hundreds of people, interested in Shadow Play. No, just the Fast Forward session.

materia

sinabey — Thu, 17 Dec 2009 01:01:05 +0000

Materia is a single player game and it is developed for the 3D programming course’s game contest. The game play was designed to mimic classical arcade game type, where the player constantly moves forward and try to avoid obstacles, and the twist was using four walls of the tunnel that game takes place within.

Unlike its simple graphics, Materia has a very heavy story. The game takes place before time, when the existence was a huge blob of energy. The player controls a particle, which travels to existence in a tunnel of elements. Each surface represents an element; fire, water, life and void. Every surface has it’s own obstacles and the more the particle stay on a surface, the more it drains the corresponding element. At each level, the player has to stay on a surface for sufficient time interval and at the end of the game, the mix of essences define the nature of the particle as it fully reaches to existence.

Astronomy + Love of Final Fantasy Series + Game Boy experience = Designing Materia

This was a collaborative project; I implemented the game play, levels and shaders, and my partner handled the models, textures and sound effects.
