Primeira etapa do projeto de construção de ferramentas artístico-interativas usando tecnologias/organismos livres..

Misturas lúdicas de bits, organismos, soldas, fios, voltz,…

Plataformas:

Arduino + Processing + PD + Protoboard + LDR + Potenciometros + peixe beta(alfa) + pdp_ctrack (rgb:15,15,0);

obra-fluxo…

obra-processo…

obra-acontecimento..

… universal sem totalidades..
