CCK module for custom code

Hi,

I am learning to work with Drupal CCK and I just wonder how many possibilities it provides us! What I need is to have a custom CCK field in which I can insert something of that:
- html code ( for example

)
- code which when opened could redirect current page to something else
- insert an object like flash

I would display this field optionally with views.
Is this possible somehow?

Thanks very much for answers!
