Extension allows to create unlimited number of product groups with as many products as you like and apply prepared templates.
You can display any product group with any template in any place on your website.

Watch it in action

As soon as you create block and template, you will be able to place it on static page, or directly in templates (phtml files) the following way:
For static page:

{{block type='pblocks/pblocks' block_id='ID_OF_BLOCK' template_id='ID_OF_TEMPLATE' }}

For .phtml file:

getLayout()->createBlock('pblocks/pblocks')->setBlockId(1)->setTemplateId(1)->toHtml(); ?>
