Sorry for resurrecting this thread but I really like the charts.
I am thinking of making a Windows 7 gadget for displaying them on the desktop. A few questions regarding this:
1) Is there any interest in this at all? After all, Windows 7 gadgets have been discontinued by Microsoft for security reasons. Still, a lot of people continue using them, myself included. The MyBitcoins gadget is quite popular, but it only shows the price, not the chart.
2) Are there any legal issues involved? The charts already bear the address of the site providing them but I'd like an explicit permission for using them not exactly for the purpose for which they were intended (as charts to put on Web pages).
3) How often do the charts refresh? I am thinking of refreshing them once a minute but if the site refreshes them less often than that, I'd like to know, so that I use a longer interval too, in order not to cause unnecessary traffic to the site.
4) Anything else I might have missed?
