Heroes Easter Egg - Another Hidden Helix

The helix can be found in a lot of places during the series. Jessica's shoulder, Dr. Chandra Suresh's program, the sword etc.
But I recently saw it hidden somewhere else after watching it again. In episode 2, where officer Parkman first discovers his ability, outside Molly's house, he is standing next to a swimming pool. For a split second you can see the symbol in the pool.
In another episode it can also be seen on Claire's school books.
