Free daily public source of (pseudo)randomness

I need to run a drawing which I would like to seed with (say) 32 bits of public (pseudo)randomness. Ideally the random seed is drawn at about midnight ET daily and is simple to find (e.g. a trusted third-party site posts a random immutable 32-bit number every day). I know that random.org has third-party drawing functionality, but ideally there is a free alternative. Are there any services that provide this? Thanks in advance.
