I advise students (undergraduate and postgraduate) and any other academics who may have stumbled across this blog by some happy accident to read the article below.
I may even have to change a few of my small idiosyncrasies ;-)
I agree that laser pointers are pointless and am a firm believer that big long sticks are the way forward as my Econ101 class will hopefully testify even if the said stick can appear unwieldy at times especially when attempting a particularly tricky powerpoint/overhead anecdote switch with the time approaching 10 to the hour.
I have immortalised this link in the sidebar with some other "sources".
