come to see my boat simulator

I made a boat simulator. It's not yet finished because there is no goal
,but say me what do you think about,
if you have some advices...
I made a "stereo" version : if you squint enough to merge the two picture
then you will see relief.(if you have a large screen then move away, it
will be easier)
download it at my site: http://perso.wanadoo.fr/gilbut/martinpage.htm (the
boat picture)
it will be quick (some seconds).
