Display specific taxonomies

I have a list of different taxonomies within a list, which can be done by the following code:

<?php wp_list_categories(array('title_li' => '', 'taxonomy' => 'project_tags', 'walker' => new Project_Walker())); ?>

I need to remove some specific (or show some of them specifically) taxonomies, not all of them as the previous code does. Something like this:

<?php wp_list_categories(array('title_li' => '', 'taxonomy' => 'project_tags', 'project_tags' => array('audiovisual','web'), 'walker' => new Project_Walker())); ?>

In the example, obviously, the taxonomies that I hope to show up, was ‘audiovisual’ and ‘web’.
There’s no problem if anyone came up with a different solution, for example, excluding all taxonomies, except for the ‘audiovisual’ and ‘web’.

Thank you!
