There's over 120 blender files here on this French page:http://www.zoo-logique.org/3D.Blender/index.php3?zoo=dld&rep=blenderfiles
Special mention: billarrays.blend
: That animation with all the cube arrays. This the original file, folks - I remember someone was asking about this in a previous thread.
FlowerOpenHooks.blend - anim of bee and flower.
rainette&lotus.blend - frog and lotus scene.
pulsing-knot.blend - animation of ribbon creation.
jeux.blend - walkthrough using game engine , get the other 4 with this name, all good.
looks like you could make a game out of this file if you can fix the stair climbing.
. . . . . and lots more, some good some bad.
Hope y'all like it.
