Big Box of Blox from Astraware might be worth checking out; it is free for the month of July. Astraware has churned out pretty good games for as long as I can remember. That’s pretty long considering the first Bejewelled I played were in monochrome (that’s black and white by the way, well technically they’re just black pixels on a greenish LCD). There’s also a fireworks program that… ehm, displays fireworks. Really, it does nothing else; aka eye-candy. If that’s your thing, get it here.
