Virtual bumper stickers

Techies are sharing their opinions about our flip-flopping president. Daily Kos offers ideas about broadcasting your opinions via wifi and Bluetooth Users Against Bush "uses bluetooth enabled devices (mobile phones, PDA's, laptop computers) to create moments of ad-hoc solidarity for people opposed to George W. Bush and his disastrous policies." Daily Kos tells of people naming their networks "WiFi Against Bush." I've also seen "George Bush lied to you" and "George Bush is a liar." Please share other creative (and tasteful) ideas for virtual bumper stickers.
