Again a great episode!

How about a small ‘real life’ application in the next screencast?

Great to see some screencasts on Griffon. Thanks for your efforts.

Some suggestions:
1) I just could not hear any audio. ( Even at max volume ). Just a faint whisper. ( Admittedly i have a pretty average set of speaker ) If you could record it at a higher volume, that would be great. It’s easy to reduce the volume if folks think it’s too high – but not the other way around.

2) If you could magnify the command-line inputs you give, it would help to see what’s going on. When you have a high-res monitor and you sit in front of it, things might look good – but it’s difficult to see what you are typing.

3) It would also be nice to see some simple but complete applications built. Could be some simple utility or tool.

On the whole, thanks for all the hard work you’ve put into these screencasts. I appreciate it.

Nice and useful introduction to griffon. The only catch is that the volume is way to low. I don’t have headphones with me and have a very hard time understanding you. But thanks for the time and effort you put into this!
