Asterixis (n.) [MeSH]
|Classification and external resources|
Asterixis (also called the flapping tremor, or liver flap) is a tremor of the wrist when the wrist is extended, sometimes said to resemble a bird flapping its wings. This motor disorder is characterized by jerking movements (as of the outstretched hands) and is associated with various encephalopathies due especially to faulty metabolism. The term derives from the Greek a, "not" and stērixis, "fixed position".
Usually there are brief, arrhythmic interruptions of sustained voluntary muscle contraction causing brief lapses of posture, with a frequency of 3–5 Hz. It is bilateral, but may be asymmetric.
R.D. Adams and J.M. Foley first described asterixis in 1949 in patients with severe liver failure and encephalopathy.

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 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 !
