I think the uptick is due to

1) TO buying some shares atleast in the open market. - most people who sold in the .50-.70's range probably picking up shares now since there seems to be support around .28 cent level

2) Olympics only 4 days away - might see a tiny run

but there doesn't seem to be people hitting the bids, so i guess i am here for the long haul. no point sellnig now, whats another year. Maybe by then there will be consistent revenue, new products, new retail placements, FDA or Approval in europe.
