Seesmic Template Tags

I would like to be able to only show the video thumbnail on the index page of my blog and have that link the Seesmic video on 'single.php'.

I can envisage this through the use of some pre-determined 'template tags' e.g. 'get_see_thumb' for the index page and 'see_video' for the single.php page

Does anyone have any idea if this is possible?
