Lettris
Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
boggle
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

M89 (ou NGC 4552) est une galaxie elliptique située dans la constellation de la Vierge, et faisant partie de l'amas de galaxies appelé amas de la Vierge. Elle fut découverte par Charles Messier le 18 mars 1781.
Elle est classée de type E0 dans la séquence de Hubble, ce qui signifie qu'elle est visuellement presque parfaitement circulaire. La galaxie est accompagnée d'une structure en forme de jet, s'étendant sur environ 100 000 années-lumière, qui pourrait être une galaxie satellite plus petite, en train d'être désintégrée par les forces de marée.
