This page lists some digital prototypes that are mostly related to language, linguistics and teaching. Listed in time order of conception.
ELTtalk bingo – next time you are at a ELT conference why not play this? : )
BNC gender words – mainly experimenting with how to extract data from xml files from the British National Corpus you may or may not find the tool of use.

Phonogon vowel chart – implementation of Mark Hancock’s PronPack a nice alternative to the Adrian Underhill chart.
