Takashi Yamamiya

A programmer, 1972 born in JAPAN

My main goal is to get programming environment be a medium of human
expression like art and literature. Computers do not only expand
ability of brain, but also reflect what we are. Like painters use
self-portrait to discover their mind, programmers use programs to discover
their thought (Ostranenie - Crossover between Art and Programming).

Our kids in the next generation will write a program to reflect their
ideas as we write journal and poem now. This requires a programming
environment which has strong enough flexibility and consistency. To
the end, I have sought various known programming technique from Object
oriented programming, Functional programming, to Formal methods, etc.

As a Squeak programmer, I have contributed some stuffs like i18n,
low level drivers, graphic design of EToys, "Demon Castle" tutorial.
And I made a couple of goodies includes ODECo, Techo, Skeleton and LanguageGame.
My background is kinetic sculpture and performance.

Old softwares


Skeleton is a tool for making mathematical and physical simulation easy way. This is an extension of Squeak etoy system, and User can operate almost with drag-and-drop. In addition to, user is not only able to make funny interactive contents like what ThingLab shows, but also to verify whether it works well with unit tests.


LanguageGame is a parser generator that has graphical user interface written in Squeak. Though parser generator is a professional tool that is used to develop a programming language. With LanguageGame, I hope that non-professional computer users,students or children will be able to learn the concept of "programming language" and to design their original language.

sculpture and performance

a Minimal Music Machine

2011 wood, copper, string

This is a musical box made of wood. Four bells are copper pipes which were cut and tuned as G, A, C, and D. One of the design goals of it was that the frame was made without any metal like screws or nails, and every parts are connected by stitches with cotton string. Imagine a world where people only know stitches for connecting materials, what kind of machines they would design? Such a condition makes an interesting challenge for its design and shape.
