Does exactly what I required.

Brown Flag

I wanted to see what OpenGL extensions are available on my iPhone and this is exactly what this does. The banners are not obtrusive, taking up a very small amount of screen and complaining about it on this free app is pathetic. The person leaving the other comment obviously feels that a developers time is worth nothing.

Buggy but nice app


Seems to be a bug in the current version where switching on fog also enables transparency - other than this it works just great!

Banner Ads Irritating

Nice enough little app, but banner ads splashed all over it for grocery stores mean I'm deleting it and going for something paid for instead.

Not worth the annoying distractions.
