A Victorian primary school recently used my IF game Six as part of a literacy activity for year six students. Some of them even became converts to IF in the process.
As part of helping to prepare this exercise, I recompiled the game to version six and set it up for online play. Six hasn't been browser-playable before. You don't get the sound and music playing it this way, but you do get the graphics.
