Keep in mind that you can always do this:

```python
frames = [VisualizationFrame(...), VisualizationFrame(...), VisualizationFrame(...)]
s = Scene(I, O, *vframes, name='my scene')
```

i.e.

```python
>>> def f(*args):
...     for arg in args: print(arg)
... 
>>> things = ['one', 'two', 'three']
>>> f(*things)
one
two
three
```
