  tanvirisraque.com · version 3: bold, and complete.
  The name, a short profile, four projects (each with its own animated object, and an app tour for
  Subah and Simpletree), then the record: about, experience, education, research, ventures, decks,
  questions, contact.
  Brand: the "ti" kit, at night (his positioning: it is always night; ink ground, cream type, one coral light).
  The token names are historical: --bone is the GROUND (Midnight) and --ink is the TYPE (Bone).
