The lamp inside I had rescued from a lighting firm a few years earlier, and as it was cast metal complete with plug and cable, this idea became really easy to realise.

The required materials were, imac G3 plastic casing
Lamp base with a bit of weight to it, complete with cable and plug.
Cable ties to secure lamp base to imac casing.
Perspex cut to size.
a print off of your desktop, printed out on OHP foil.
glue (to glue the case together.
1 energy saving light bulb (they don't create to much heat.)
The bulb can be easily changed through the access cover used to remove the bottom cover screws (and radiation shield when you have to change the bios battery.
Glue the top casing parts together, with the perspex cut to shape on the inside of where the CRT used to display. Tape or glue your OHP foil to the inside as to give the impression that the imac is on when the lamp is on. If you can get milk or frosted perspex, then with a little talent you can paint the boot up screen from the inside, not forgetting as to which way the apple should face when it is finally glued together.
Meanwhile fix the lamp base into the bottom case with the cable ties, screw in the bulb, and glue the top case to the lower case.
The cable and plug can be fed out of the hole where the power cord used to be plugged into.
I also had the plastic casing from the ports and of course glue them also in place (headphone and microphone jacks included.
Hopefully this will please any Mac fan who is sad about the demise of their old imac, this is of course the slot loading model, so you muss not forget to remove the front part of the tray by tray loading models, and glue them into place as well.
