Dunno what to write. So here's a snake in python (uses pygame):

while"_"in globals()or(map(globals().__setitem__,"lain_snake",[(640,480),1,1,1,
15,globals().__setitem__,tuple]+map(__import__,("pygame","random","time"))),s( 
"P",lambda:x and I()or(i or(s("b",b[1:]+[o]),C(b[0],0),s("o",n(o[j]+d[j]*_ for 
j in[0,1])),(s("x",o in b or any(not 0<=o[j]<=l[j]-_ for j in[0,1])))or x or C(
o)),[g.type==12 and exit()or g.type==2 and K(g.key)for g in a.event.get()],o==f
and(b.append(f),F()),e.sleep(0.05))),s("I",lambda:(a.init(),s("y",a.display),  
map(s,"ixbdow",(1,0,[],(0,0),n(x/2-x/2%_ for x in l),y.set_mode(l))),C(o),F(), 
y.flip())),s("F",lambda:(s("f",n(k.randrange(0,x-_,_)for x in l)),C(f,255<<16))
),s("C",lambda r,c=0xff00,h=1:h and C(r+(_,)*2,c,0)or(w.subsurface(r).fill(c),y
.update(r))),s("K",lambda k:(0<k-272<5 and(lambda v:(v[0]+d[0]or v[1]+d[1])and 
s("d",v))(((0,-1),(0,1),(1,0),(-1,0))[k-273]),s("i",k==32))),I()):P()
