Is there an easy way of doing this? for example my list is:

```
nlat=10
mylist = []
for x in range(0,nlat):
for y in range(0,nlat):
disk=sphere(pos=(x*s,y*s), radius = r, color=(0,1,9))
mylist.append(disk)
```

or is it impossible to place objects, such as a sphere from vpython into a numpy array?, perhaps i could just put the x,y co-ordinates into a numpy array?
