R\u00e9flexion<\/em> est une installation vid\u00e9o projet\u00e9e, son titre utilise la polys\u00e9mie du terme. Tout d\u2019abord avec son syst\u00e8me de capture vid\u00e9o, elle restitue visuellement l\u2019espace dans lequel elle est expos\u00e9e comme un miroir. Puis, dans un deuxi\u00e8me temps, elle t\u00e9moigne du cheminement des pens\u00e9es qui m\u2019ont conduit \u00e0 son \u00e9laboration, des r\u00e9flexions sur notre conscience du temps, sur la nature du temps.<\/p>\n

R\u00e9flexion<\/em> est constitu\u00e9e principalement d\u2019un programme qui capture en temps r\u00e9el des images pour les analyser. Le programme interpr\u00e8te les \u00e9carts de luminosit\u00e9 et d\u00e9coupe la capture vid\u00e9o en un certain nombre de faces. Il replace ces faces sur des cubes dans un espace 3D en pla\u00e7ant les cubes les plus lumineux en avant.<\/p>\n

Cette installation interroge notre rapport au temps, elle retransmet des cubes vid\u00e9o avec un d\u00e9lai d\u2019une dizaine de secondes. Ainsi l\u2019image du spectateur est d\u2019abord capt\u00e9e par le dispositif avant que celui-ci prenne conscience que cette captation est retransmise.<\/p>\n

Ce processus de capture en temps r\u00e9el et de retransmission en diff\u00e9r\u00e9 qui est une citation de Going Around The Corner<\/em> de Bruce Nauman ou Present Continuous Past(s)<\/em> de Dan Graham, o\u00f9 le sentiment de la dur\u00e9e<\/em> d\u00e9velopp\u00e9 par Bergson dans l\u2019\u00c9volution Cr\u00e9atrice<\/em> (avec l\u2019exemple du sucre qui fond dans l\u2019eau) est mis en ab\u00eeme. En effet dans ce livre Bergson \u00e9met l\u2019hypoth\u00e8se que les objets, les choses ont une dur\u00e9e similaire \u00e0 notre dur\u00e9e int\u00e9rieure.<\/p>\n

\nD\u00e9tendons-nous maintenant, interrompons l\u2019effort qui pousse dans le pr\u00e9sent la plus grande partie possible du pass\u00e9. Si la d\u00e9tente \u00e9tait compl\u00e8te, il n\u2019y aurait plus ni m\u00e9moire ni volont\u00e9: c\u2019est dire que nous ne tombons jamais dans cette passivit\u00e9 absolue, pas plus que nous ne pouvons nous rendre absolument libres. Mais \u00e0 la limite, nous entrevoyons une existence faite d\u2019un pr\u00e9sent qui recommencerait sans cesse, plus de dur\u00e9e r\u00e9elle, rien que de l\u2019instantan\u00e9 qui meurt et rena\u00eet ind\u00e9finiment. Est-ce l\u00e0 l\u2019existence de la mati\u00e8re\u2009? Pas tout \u00e0 fait, sans doute, car l\u2019analyse la r\u00e9sout en \u00e9branlements \u00e9l\u00e9mentaires dont les plus courts sont d\u2019une dur\u00e9e tr\u00e8s faible, presque \u00e9vanouissante, mais non pas nulle. On peut n\u00e9anmoins pr\u00e9sumer que l\u2019existence physique incline dans ce second sens, comme l\u2019existence psychique dans le premier.\n<\/p><\/blockquote>\n
