```
public Sequencer(Thumbelina thumbelina)
```
    Creates a new instance of a Sequencer.
    
    Parameters:
    
    thumbelina - The object to push images to.
- Method Detail
  - reset
```
public void reset()
```
    Clears the pending images list.
  - random
```
protected java.awt.Point random(java.lang.String url,
                                int width,
                                int height)
```
    Compute a random point to load the image. Generate a random point for one of the corners of the image and then condition the numbers so the image is on screen.
    
    Parameters:
    
    url - The url this picture was fetched from. Used in computing the random position, so the picture is always placed in the same location, even when refetched.
    
    width - The width of the image.
    
    height - The height of the image.
    
    Returns:
    
    The random point to use.
  - add
```
public void add(java.awt.Image image,
                java.net.URL url)
```
    Add an image to the pending list.
    
    Parameters:
    
    image - The image to add.
    
    url - The url the image came from.
  - add
```
public void add(java.awt.Image image,
                java.net.URL url,
                boolean background)
```
    Add an image to the panel.
    
    Parameters:
    
    image - The image to add.
    
    url - The url the image came from.
    
    background - If true, just add to pending list.
  - place
```
protected void place(Picture picture,
                     boolean add)
```
    Place a picture in the display area. Places the picture at a random location on screen.
    
    Parameters:
    
    picture - The picture to place on screen.
    
    add - If true, the picture is added to the history.
  - run
```
public void run()
```
    Display pictures from pending list with delay between. If the list is empty it waits on the pending list for new pictures.
    
    Specified by:
    
    run in interface java.lang.Runnable
    
    Overrides:
    
    run in class java.lang.Thread
  - getDelay
```
public int getDelay()
```
    Getter for property delay.
    
    Returns:
    
    Value of property delay.
  - setDelay
```
public void setDelay(int delay)
```
    Setter for property delay.
    
    Parameters:
    
    delay - New value of property delay.
