I asked TOMHTML if he ever saw this and the answer was "non".

I found on Blogoscoped Forum a strange ad :

Did anyone have saw this before ?

it's really... weird. I remember something like that (or nearly) but it was on iGoogle so... :-S

I have seen this also

Maybe they're still testing the gadget ads. Google also had an ad created by LabPixies for Gmail:
