Everybody knows this situation: there is a strong video projector light, people sit and wait for some show or talk and someone will start to make hand shadows. It is almost impossible to detain people from playing this facinating game of <a href=\"http:\/\/en.wikipedia.org\/wiki\/Projection_%28mathematics%29\">projections<\/a> from <a href=\"http:\/\/en.wikipedia.org\/wiki\/Graphical_projection\">3 to 2 dimensions<\/a>. <\/p>\n<p>Cultural life has taken account of this fact. This manifests itself in the <a href=\"http:\/\/www.centres.ex.ac.uk\/bill.douglas\/Schools\/shadows\/shadows7.htm\">chinese<\/a> and javan or <a href=\"http:\/\/www.karagoz.net\/english\/shadowplay.htm\">turkish<\/a> (which seems to come from ancient egypt) shadow play and extends  to <a href=\"http:\/\/www.henri-riviere.org\/v2\/\">Henri Riviere&#8217;s shadow theatre<\/a> at the <a href=\"http:\/\/www.lechatnoir.free.fr\/chat_noir\/page_269.htm\">black cat<\/a> (where also one of my favorites <a href=\"http:\/\/en.wikipedia.org\/wiki\/Erik_Satie\">Erik Satie<\/a> worked). <\/p>\n<p>Or- in  more modern times: shadows reach from  the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Pinscreen_animation\">pinscreen animations<\/a> of <a href=\"http:\/\/en.wikipedia.org\/wiki\/Alexandre_Alexeieff\">Alexeieff and Parker<\/a> to optical experiments with sculpture like the ones of <a href=\"http:\/\/www.illusionworks.com\/mod\/fukuda.htm\">Shigeo Fukuda<\/a> (also featured by <a href=\"http:\/\/www.amazon.com\/gp\/product\/1402705778\/102-0169672-7776979?v=glance&#038;n=283155\">Al Seckel and Douglas Hofstadter<\/a>) and  hip YBA (young british artists) Tim Noble and Sue Webster with their very nice <a href=\"http:\/\/www.modernartinc.com\/timnoble\/\">junk-love-shadow-light sculptures<\/a> (e.g.  Dirty White Trash with gulls) sold by <a href=\"http:\/\/www.saatchi-gallery.co.uk\/artists\/noble_webster.htm\">Saatchi Gallery<\/a> (where one could may be mention that this gallery is known for their <a href=\"http:\/\/kunst-blog.com\/2006\/06\/extremely_saatc.php\"> inventive politics to promote their blog<\/a>).<\/p>\n<p>A projection usually means to leave away information or -like in the case of shadow puppets- to impose that there  seems to be more information. This may lead to illusions.
