Method 1, modified so that the 100 points must be unique..
<lang lua>t, n = {}, 0
for y=1,31 do t[y]={} for x=1,31 do t[y][x]=" " end end
repeat
x, y = math.random(-15,15), math.random(-15,15)
rsq = x*x + y*y
if rsq>=100 and rsq<=225 and t[y+16][x+16]==" " then
t[y+16][x+16], n = "██", n+1
end
until n==100
for y=1,31 do print(table.concat(t[y])) end</lang>
