welcome. let us introduce ourselves.

  256 = 0x100 = 0b100000000 = 2^8

one byte holds 256 values. small, but enough to represent anything.
that's the idea behind our name: 株式会社256技研

  "Giken" (技研) = short for "Gijutsu Kenkyujo" (技術研究所)
  think of it as "Tech Lab"

so, 256 Tech Lab. we make the world 256x more fun with code.
not a slogan — a constraint we build against.

founded by 岸田 涼.
