Slams can be pre-planned and expected to have been rehearsed/prepared.
They should be quick, simple and engaging. Look for something that can more generically be used. It can be geeky or just plain useful. Examples:
- Useful Chrome Extension
- Useful 'Lab' or Add On
- Unique uses for apps like Draw or Sheet
